Package: coturn Version: 4.5.1.1-1.1+deb10u1 Since the last update (from 4.5.1.1-1.1 to 4.5.1.1-1.1+deb10u1) coturn server does not work anymore.
The file /var/log/syslog contains : Jun 29 18:25:08 rex turnserver: 0: Cannot bind TLS/TCP listener socket to addr W.X.Y.Z:443 Jun 29 18:25:08 rex turnserver: 0: Trying to bind TLS/TCP listener socket to addr W.X.Y.Z:443, again... I found out an issue on GitHub for this : https://github.com/coturn/coturn/issues/421 I modified the file /lib/systemd/system/coturn.service to include AmbientCapabilities=CAP_NET_BIND_SERVICE to the [Service] section and the coturn server is working again. I hope It can help people. Best regards Benoît
