Debian 11, impossible to make coturn work

[tostra]

Installed to 7 days old Linux uptodate Debian 11 this happened:

The stun works but turn no way(it's down). I have no idea, this "socket: Protocol not supported"; error probably has to do with it(I have some old centos running old coturn,there is no such message).

I have no way of knowing it, what it is. Anyone can help me out, because I can not think of anything no more.

Anyone ever installed new coturn to Debian 11 successfully?

I have also installed successfully janus-gateway, can be there any conflicts.
