Good day.
The log contains
"info" : "Failed by ICE timeout"
. The message means DTLS/ICE connection is not established between client and server. That usually happpens when media UDP ports (31001-32000/udp by default) is closed, so client can't connect to these ports to send or receive media traffic.
Please check ports availability as described
here.
If ports seems to be available, it means ISP blocks DTLS (to prevent Tor connections). In this case, using
TCP transport may help.
