WebRTC port already in use. Any port!

[p3dr01984]

Hello I am on go2rtc Version: 1.9.10, running on host network in Unraid 7.1.4.

First of all, there is nothing else on the default port 8555 No matter what port I try for WebRtc, I always always get address already in use, such as: ERR github.com/AlexxIT/go2rtc/internal/webrtc/webrtc.go:48 > error="listen udp 192.168.1.100:8555: bind: address already in use" No issues with RTSP or MSE

I did disable Frigate and home Assistant already.

What else can I try to fix this?

Thank you.

Google how to check which program is using a port in Linux.

[p3dr01984]

Thank you for your reply @AlexxIT . But as I said in the first post, no other program is using that port. ANY port I try it says it's already in use

I have no clue at this point

1. Show your config (webrtc part)
2. When you get this error? On app start? On stream strart?

[p3dr01984]

I get the error on app start.

api:
  listen: ":8084"

rtsp:
  listen: ":8556"

webrtc:
  listen: ":8991"          #or any port 
  candidates:
    - 192.168.1.100

thank you very much for helping out

Try to add your server IP-address to listener.

holy cow that did it. I know this was a lame issue, but thank you so much for helping out anyway!

In any case, it's a bug. The port should work just fine.

I had the same issue after upgrading to 1.9.10. Thank you!

I want to bump this :)

[AlexxIT]

@TokeyChan If you have IPv6 address there - it's another issue. If this error happened for any port (you should try several) - it's another issue. In other case - it's your problem that the port is actually occupied by another application.

[TokeyChan]

I tried multiple ports and none made it possible to use. Hence I think it is the exact same issue that the original poster had

[AlexxIT]

My bad. Any port is this problem. Have you tried the latest version of go2rtc?

[TokeyChan]

I'm using the newest available docker container, which is v1.9.11

i'm also getting this error in v1.9.12
