signalserver in combination with coturn #64

First I have installed the flutter-webrtc-server (without coturn) and it was running fine in most scenarios with flutter-webrtc on mobile. I followed the instruction at: https://larrylisky.com/2020/05/22/implementing-flutter-webrtc-client-and-server/

As a next step I installed coturn (on the same machine). I also tested my Coturn instance successfully with Trickle ICE and it seems to run fine. I followed the instructions at https://meetrix.io/blog/webrtc/coturn/installation.html

But I can no more start the flutter-webrtc-server now. It says it failed to create TURN server listener: PNC Failed to create TURN server listener: listen udp4 0.0.0.0:3478: bind: address already in use panic: Failed to create TURN server listener: listen udp4 0.0.0.0:3478: bind: address already in use

I can confirm that I use the following configurations: For flutter-webrtc-server in config.ini: ... bind=0.0.0.0 port=8086 ...

For Coturn in turnserver.conf: ... listening-ip=0.0.0.0 listening-port=3478 ...

It would be great if anybody could help me out and point me in the right direction. What do I miss here?

Thank you so much for your project..I enjoy it very much exploring webrtc...

your udp port 3478 is already in use since coturn uses it. i'm assuming you set your flutter-webrtc-server turn port to 3478 as well, did you not? in that case, choosing a different turn port (in config.ini) should solve your issue. note that flutter-webrtc-server starts its own turn server (pion/turn) on the port that you provide in config.ini.

Yeay, thanks for letting me know. It works like a charm. Thank you so much again!
