Seems like the problem is that you are using a port below 1024 for coturn. As these ports need coturn to be started as root or as an alternative you can modify the file /lib/systemd/system/coturn.service and include AmbientCapabilities=CAP_NET_BIND_SERVICE in the [Service] section. Afterwards the coturn server should be working again.
