Hello

Make sure UDP ports open in range [31000-32000]
You can also check ports using nc tool from external server

If it does not help, please provide ssh access and RTSP URL privately using this form

I think, it didn't help.
this problem only occurs on latest chrome browser v87.0.4280.66.

Is there a way to request help without giving ssh access ?

According to your logs, you are using too old WCS build 5.2.115. This build uses DTLS 1.0 by default while establishing WebRTC connection. Latest Chrome builds (and Chromium based browsers too) does not support DTLS 1.0 at all.
So we highly recommend to update at least to build 5.2.798 which is running on our demo server, or to newest build from this page

Thank you, Update from WCS build 5.2.115 to build 5.2.798 solved the problem on Chrome.
