Hi @Yavuz Coşar

Based on the information you provided here, it’s not easy to see what the problem can be. I see that the RTP handlers does 4 attempts to bind to the port, and after that it seems to give up. Can that point to the real cause? The raw logs (found in the /logs folder of your Wowza installation) may be better for analyzing this.

If you want, you can join the Wowza Slack community via [https://www.wowza.com/slack](https://www.wowza.com/slack), and discuss your problem with fellow-experts in the #webrtc channel.

Hello @Yavuz Coşar

This could come down to ports not being open in the firewall or port forward if going across networks and/or your WebRTC configuration files.

Here are common ports that are used for WebRTC.

TCP: 1935, 443, 9443

UDP: 6970-9999 and sometimes up to 65535
