Live Stream Not Working? How to Troubleshoot Live Streaming Issues with Broadcasting

live streaming troubleshooting

When it comes to live streaming, there are many moving parts. Broadcasters need a workflow for filming the live event, encoding or transcoding the files, delivering the video to users, and allowing playback by viewers. While a modern live streaming platform makes it simple to get started, issues can still pop up. 

Even though only 2.6% of live streams fail to start—the biggest problem with live video now—businesses can still lose viewers when streams have issues. If something goes wrong, therefore, broadcasters must respond with error handling best practices for streaming. 

That’s why we’ll take a deep dive into how to troubleshoot video streaming issues immediately. Our suggestions follow a typical streaming workflow from video encoding to delivering and playback.

Let’s see what you can do if your live stream is not working correctly. Let’s get right into it so you can troubleshoot your live streaming issues confidently.

Why Isn’t My Live Streaming Working?

First, let’s explore some of the reasons why your live stream might not work as planned. Video streaming issues can occur at any point during the process, so it can be helpful to understand all the steps involved in successful live streaming.

Here are some of the most common reasons for live streaming failures:

1. Using the Wrong Technology

Whether you’re a vlogger doing a simple live stream from your bedroom or a broadcaster doing an elaborate multi-camera stream, you need to use the proper hardware and software.

A lack of preparation is one of the most common reasons for live stream not working. For instance, for live streaming a music event, you need to ensure that everyone musician is properly mic’d up, that the audio is being mixed properly, and that all the cameras are capturing good-quality video.

2. Not Enough Bandwidth

Nothing will drive your viewership down quicker than a live stream with a lot of buffering. Even one short buffering interruption can lower your viewership by nearly 40%. That’s why you need to test your internet connection before you start streaming.

But even with enough bandwidth, your live stream is not working, possibly due to a lack of speed. For example, most Internet service provider plans in the U.S. have an upload speed of 5 Mbps or less. That means you can only live stream video at 720p resolution with a bitrate of 3 Mbps or lower.

3. Audio and Video Not Synced

If your audio and video are out of sync, it can be extremely jarring for viewers. An issue usually causes this stream broadcast unexpected error with the encoder software, but poor internet connections or playback issues can also cause it.

To fix this problem, check your encoder settings and ensure the audio and video bitrates are identical. Simply restarting your encoder software can also fix your video streaming issues. We’ll discuss this process in more detail later. Also, checking your connection and playback devices can help too.

4. Live Streaming Mistakes to Learn From

Mistakes are bound to happen during live broadcasts. Sometimes, you can’t do anything about it. You probably remember this infamous (and hilarious) BBC interview from a few years back. If not, you remember when a power outage disrupted the Super Bowl feed.

Luckily, you can avoid some mistakes and your live stream not working can be avoided.. With enough preparation, you can ensure your live stream goes off without a hitch. Here are some common mistakes broadcasters make and how to avoid them.

5. Not Testing Your Equipment

One common live streaming mistake is not testing your equipment before going live. That can be a costly mistake, especially if you’re using new or rented equipment.

To avoid your live stream not working, always test your equipment before going live.

That way, you can identify and fix any potential issues. The same goes for software. For instance, if you’re using a new live streaming platform like Dacast, it’s important to try it out, learn the ins and outs, and test it with your equipment before going live.

6. Weather Issues

No matter in what country you live, the weather can always be a potential issue. For example, if you’re live streaming an outdoor event and it starts raining, you need to have a plan in place. The last thing you want is your equipment damaged due to bad weather conditions.

You need to listen to weather reports in the days leading up to your live streaming event and plan accordingly. If it’s windy outside, make sure your equipment is properly secured. If it’s raining, have a plan to keep your equipment dry.

7. Unintended Eavesdropping

What’s worse than live streaming not working? Having your surroundings create unexpected problems. When live streaming, you have to be aware of your surroundings. That’s because anything – and anyone – near your live streaming setup can be picked up by the camera and microphone.

For example, if you’re conducting an interview and someone walks by and starts talking loudly, the microphone and broadcast will pick up audio from your viewers. To avoid this problem, you need to be aware of your surroundings and, if possible, have a dedicated area for your live streaming setup.

8. Power Outages

No matter how well you prepare, there’s always the potential for a power outage. Between 2011 and 2021, the annual number of power outages caused by bad weather increased by nearly 80%. When the power goes out, your live stream will go down too.

So, it’s important to have a backup plan in an emergency. For example, you can use a battery-powered UPS (uninterruptible power supply) to keep your live streaming equipment running for a few hours. You can also use a generator to power your equipment if the power is out for an extended period.

10 Ways to Troubleshoot live streaming Issues

When live streaming, your environment may cause some issues. But as we all know, live streaming technical difficulties can give you a much stronger headache. So, how can you decrease the chances of a live stream not working

Here are ten ways to troubleshoot live streaming issues:

1. Check Encoder Settings

video encoder and transcoding settingsDouble-checking for the correct encoder settings is the best way to ensure a quality live streaming experience.

Most live streams require a hardware or software encoder to convert RAW video files into a format suitable for streaming. Modern encoders, however, have a lot of settings to choose from, and an improper configuration could cause issues.

That’s a common live stream problem, so we always suggest you double-check your encoder settings if your live stream isn’t working correctly. 

That’s why at Dacast, we recommend the following settings.

VIDEO CODECH.264 (x264 may work)
FRAME RATE25 or 30
KEYFRAME INTERVAL2 secs (or 2x frame rate)
AUDIO SAMPLE RATE48 kHz (48,000 Hz)

These settings are a baseline requirement for a live streaming setup with Dacast. That’s because they’re ideal for ensuring compatibility with the Dacast video platform and a wide range of user devices.

If you don’t see a message that indicates the encoding hardware or software is streaming to primary, there could be an issue with your encoder settings.

First, you’ll want to ensure your live stream encoder is pointed at your streaming server, which delivers the stream to end-users. The encoder’s “Stream Name” and “Stream URL” should match the values provided by your Online Video Platform (OVP)

If the encoder only has a single URL field, you’ll need to use the ‘Backup URL’ under the ‘Other RTMP encoders’ section of Dacast’s encoder software setup page.

If you’re using encoding software that’s not integrated with Dacast, you may also need to enter a login and password during configuration. That information—different from your Dacast account—will also appear on the Dacast encoder setup page.

When multi-bitrate streaming, some encoders require specific names for each stream. However, the requirements may be different, depending on which encoder you’re using. If there still seems to be an issue with your encoder, we recommend trying another option, like OBS Studio.

If an encoder software error occurs while streaming, try the steps above to address the issue.

2. Confirm Bandwidth Availability

Bandwidth measures the data transfer rate, which varies depending on streaming quality, viewers, and more. That means some streams will use more traffic than others, and you’ll need to analyze your bandwidth usage and availability if you’re experiencing live streaming problems

Every Dacast plan has a limited amount of bandwidth available for streaming. Once you’ve hit the limit, your stream will stop unless you’ve set up overage protection. You can also upgrade your video bandwidth anytime, but it won’t go into effect mid-stream.

That is why it is important to check and ensure you have enough bandwidth before starting your live stream to avoid this streaming issue. 

You can check if you’ve hit the limit by viewing the “Upgrade my plan” option within your Dacast account. You can also use our calculator to determine which plan matches your bandwidth requirements based on broadcast frequency, viewers, stream length, and quality.

3. Compare Upload Speed & Bitrate

video bandwidth upload speeds
There needs to be the right ratio between upload speed and bitrate.

The bitrate of a stream is a measurement of the number of bits required to be transmitted per second. Transferring the stream to your OVP needs to be at least as fast as the video stream’s bitrate. Streams with bitrates that exceed bandwidth could suffer from lags, buffering, or outages.

If you’re using adaptive bitrate (ABR) streaming, your total bitrate is the sum of every bitrate you’re streaming simultaneously. We recommend keeping this amount at less than half of your upload speed because network conditions often fluctuate throughout the day.

You can test your upload speed using If your steam’s unable to maintain a stable broadcast, you should compare your upload speed to the total bitrate. Then, adjust the bitrates included in your streaming profile to see if it helps.

You can also improve your upload speed by using a wired connection, increasing your internet plan, moving your encoder closer to the router, or limiting the WiFi usage of other devices on the network.To do this, you need to check with your Internet service provider. 

You should adjust your total bitrate and upload speed until you find a balance that offers high-quality streams without issues.

Getting the right bitrate set-up will help you avoid quality issues when live streaming. 

4. Turn Live Channel On

When broadcasting with Dacast, you’ll need a live channel turned on and configured properly. The channel settings determine the enabled features, viewer restrictions, the video player’s branding, and more.

For example, set up a channel to stream to an HTML5 video player, a low-latency live channel, or a playlist channel for a continuous series of videos. Channels give broadcasters full control over how their video content reaches end-users.

You’ll need to create a live channel within the Dacast dashboard to deliver your encoded video stream to users. Live channels are set to off by default, so a simple mistake is forgetting to enable them before the stream starts.

If the encoder is running, but the video preview is black, make sure you’ve turned the correct live channel on within the Dacast dashboard.

That is an easy streaming problem to fix!

5. Open Streaming Ports & Firewall

video streaming ports and firewall
Make sure your ports and firewall aren’t blocking the stream.

While most broadcasters can begin streaming immediately, sometimes certain ports are closed by their IT team or a firewall. In addition, your PC or network may sometimes have an integrated firewall that automatically blocks the required ports. 

Firewall blocking a video stream is a common issue that we can help you fix! 

If there are issues, you should first check if port 1935 is open when streaming troubleshooting. That’s the default port for RTMP and is necessary for your encoder to transfer the stream to Dacast. In addition, the video platform will also attempt to use port 80 or 443 as a backup. That’s why ensuring all three ports remain open is a good idea.

For Mac users, you can check which ports are open by opening the Network Utility. From there, enter your IP address and click scan. After a few moments, you’ll see a list of open TCP ports.

Windows users can check their open ports using the Command Prompt. Type in the command ‘netstart a’ and press enter. Any ports that appear with the LISTENING state are open already.

If one or more of the necessary ports are closed, you’ll likely need to contact your IT team to get them opened manually.

6. Review CDN Status

A content delivery network (CDN) is a set of worldwide servers used to distribute content. These servers cache the video content (or other data) close to users to shorten the transfer distance or last-mile delivery. That can greatly reduce the latency of streaming video.

While content delivery networks (CDNs) are meant to improve streaming video performance, they can still have issues. Some CDNs like Cloudflare have experienced outages in the past

Once video content is sent to the Dacast platform, it’s automatically transferred to a CDN and distributed amongst its servers. That means Dacast users have little to worry about when it comes to managing the CDN.

You can check Down Detector or a similar site if your viewers in certain regions are experiencing issues, as there could be CDN servers down. If you believe the CDN is down or it’s not functioning correctly, contact us, and we can investigate the issue. It’s not a common streaming issue, but it can occur. 

7. Verify Embed Code For Video Player

When using an OVP like Dacast, it’s usually straightforward to embed videos across the Internet on websites or within social media posts. For most broadcasters, copying and pasting the embed code provided within the Dacast dashboard is all it takes to share video content.

There are two types of embed codes available: iFrame and JavaScript. You can insert either of these into HTML to integrate live streaming nearly anywhere around the web.

You can verify that the embed code was copied correctly by checking the page source code. Right-click on the page and choose ‘View Page Source’, then search for ‘Dacast’ within the markup. Compare this to the embed code within the Dacast dashboard and recopy it if necessary.

That’s an easy live streaming issue to fix by following the directions above. 

8. Ensure Video Player Compatibility

html5 video playerEnsure your streaming profile is compatible with the user’s video player.

Today’s viewers watch live streams across various devices with different video player implementations. That means you need to use a streaming protocol compatible with a wide range of video players and devices.

For most broadcasters, that means using HTTP live streaming (HLS), which is compatible with any HTML5 or Video.js-based video player. That includes Dacast’s video player that’s also ready for nearly any device.

In addition, most browsers are phasing out the Flash Player, so if you’re streaming over the RTMP protocol, some users may not be able to watch. If you’re getting user complaints, check which browser and device they use to access your stream.

Ensure your streaming profile is compatible with the video players that your viewers use so that you’re capable of reaching your entire audience.

9. Inspect Viewer Restrictions

Geographical or domain-specific restrictions are critical for preventing piracy and complying with regulations in a particular region. For example, broadcasters can limit where the stream is viewed and which websites can embed the video.

If viewers can’t see your live stream, they should be able to, but you should ensure your restrictions are configured properly. You may be inadvertently preventing your audience from accessing the stream.

Within Dacast, all countries can access a stream unless you create a list of countries you want to receive the broadcast. So, make sure you haven’t left off any country your target audience may be viewing from.

Similarly, you’ll want to confirm that any sites you want to display the live stream are included on the list of allowed referrers within Dacast. It’s also important to note that these restrictions only work with JavaScript players and not with iFrame embeds.

If a viewer can’t see your content in a particular country, but other viewers can access it, viewer restrictions are most likely the streaming issue they are encountering. 

10. Switch Streams

switch streamingSwitching between current and backup streaming channels is an ideal way to troubleshoot your professional-grade broadcast.

If none of the previous solutions fix your live broadcast, we recommend trying a backup stream or creating a new one from scratch.

Dacast provides a backup stream URL nearly identical to the primary URL, but there’s ‘b’ at the beginning instead of ‘p.’ Replace this in your embed codes and test the backup stream’s playback again.

We suggest creating a new stream from scratch if the backup live stream’s not working. Sometimes, you may notice settings you misconfigured the first time. 

Finally, if all your live streaming troubleshooting doesn’t help, feel free to contact technical support, which is available to Dacast users 24/7. The Starter Plan includes chat support, while the Pro and Premium Plans also provide phone support.


There you have it. If you were wondering, “why won’t my live stream work?” before reading this, we hope you found your answer. Remember, experiencing live streaming problems isn’t anything out of the ordinary.

It may require checking your connection speed, contacting your Internet service provider, or tweaking your encoder settings, but you’ll be able to do it.  

Brands should implement a robust and resilient live stream workflow they can rely on in the future. The last thing a broadcaster wants is issues during a live stream that impact the user experience. That said, knowing how to troubleshoot live streams is critical for companies.
