Symptoms: OBS Stream Keeps Disconnecting or Freezing

When this issue occurs, you may notice one or more of the following symptoms:

The stream suddenly stops during broadcasting
OBS displays a disconnection error
The stream freezes while audio continues
The broadcast reconnects repeatedly
Viewers report buffering or stream interruptions
The bitrate drops to zero during streaming

These symptoms indicate that OBS is having trouble maintaining a stable connection to the streaming server.

Affected Users

This issue can affect many different types of streamers, including:

Gamers streaming on Twitch
YouTube live stream creators
Podcast and talk show broadcasters
Online educators hosting live classes
Users streaming gameplay or screen recordings
Anyone using OBS for live broadcasting

Both beginners and experienced streamers may encounter this problem, especially when streaming with high-quality settings.

Causes of OBS Stream Disconnection or Freezing

1 Unstable Internet Connection

The most common cause of streaming interruptions is an unstable or slow internet connection. Streaming requires a consistent upload speed, and any fluctuations can cause OBS to disconnect.

2 Bitrate Set Too High

If your streaming bitrate exceeds your internet upload speed, OBS may struggle to maintain the stream, resulting in freezes or disconnections.

3 Incorrect Streaming Server

Connecting to a streaming server that is far from your location can increase latency and cause unstable streaming.

4 High CPU or GPU Usage

If your computer is under heavy load from games or other applications, OBS may not be able to encode video properly.

5 Firewall or Network Restrictions

Some firewalls, antivirus programs, or network restrictions can interrupt the connection between OBS and the streaming platform.

6 Streaming Platform Server Issues

Occasionally, the problem may occur because the streaming platform’s servers are experiencing technical difficulties.

Solutions: How to Fix OBS Stream Disconnecting or Freezing

1 Test and Improve Your Internet Connection

A stable internet connection is essential for streaming.

Run an internet speed test
Make sure your upload speed is sufficient for your bitrate
Restart your modem or router
Use a wired Ethernet connection instead of Wi-Fi

2 Lower Your Streaming Bitrate

If your bitrate is too high for your internet connection, reducing it can stabilize your stream.

Recommended bitrates:

720p streaming: 2500–4000 kbps
1080p streaming: 4500–6000 kbps

3 Change the Streaming Server

Using a closer streaming server can improve connection stability.

Open OBS Settings
Select Stream
Choose a different server location

4 Close Unnecessary Applications

Programs running in the background may consume system resources needed by OBS.

Close web browsers
Stop background downloads
Exit unnecessary applications

5 Allow OBS Through Firewall

Ensure that OBS is allowed through your system firewall.

Open your firewall settings
Add OBS as an allowed application

6 Run OBS as Administrator

Running OBS with administrator privileges can improve performance and prevent certain streaming issues.

7 Check Streaming Platform Status

If everything on your computer appears to be working correctly, check the status page of your streaming platform to see if there are any server outages.
