[Solved] Problem using Talk with Coturn - TLS

Hello,

I got a little problem to implement TURN server configuration with TLS
I start to configure it without and it’s working fine. Then I tried to switch to TLS.

I comment
#listening-port=3478

Uncomment
tls-listening-port=5349

and add certificate (produced by certbot for my nginx/nextcloud conf)
cert=/etc/letsencrypt/live/domainname.com/cert.pem

and the private key.
/etc/letsencrypt/live/domainname.com/privkey.pem

Port forwarding changed in the router to reflect port change on the configuration.

But it’s not working like that.
I someone know what I did wrong ?
Thanks for you help.
