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
Please feel free to use the Livestreaming Slack Channel as suggested and if you would like to open a support case here’s the link.
Support files that is needed for review.
[install-dir]/conf
[install-dir]/logs (only latest logs showing connection attempts is needed)
If you are not sure how to get this information please see the following tutorial.https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux
