Hi,

great util, makes troubleshooting stun/turn way easier. But I see different results when I'm using

./stunner info -s server.domain.tld:443 --protocol udp --tls

without the --tls it succeeds, so I don't think its a firewall issue. But with the --tls I'm getting an error that the server doesn't not support stun/udp/tcp. But if I connect my Nextcloud Talk instance with turns on udp, it says ICE is succesfull. With the protocol tcp I also don't have any issues.

I'm using coturn v4.5.2-3.1, they seem to be confirming to the RFC's:
https://github.com/coturn/coturn/blob/master/README.md

Can you elaborate on this?
