Describe your issue

I can’t see videos stream when I connect with GSM connection, while I have no issues using residential WiFi.

It seems to come from a TURN/STUN issue, so I tried to instal coturn but situation still the same.

Any advices on setting up MiroTalk properly ?

Thanks !

After installing Coturn, have you updated /var/www/mirotalk/.env with appropriate entries?

See STUN and TURN configuration part

Hi,

Ok, thank you for pointing this. Unfortunately, even after filling with values given by Coturn installation page:

TURN_SERVER_ENABLED=true # true or false
TURN_SERVER_URL=turn:visio.<mydomain.tld>:5349
TURN_SERVER_USERNAME=turnserver
TURN_SERVER_CREDENTIAL=<password>

This being said, I’m testing the Coturn server itlsef using this page Trickle ICE and it does not respond properly.

Maybe it comes from my nat rules, I forwarded:

  • tcp 5349
  • udp 49152:65535

Any suggestions ?

When displaying Coturn app on WebAdmin it should display all the detail on TURN/STUN configuration (the file linked is full of placeholders YunoHost will fill on actual admin interface), including the actual domain to use, port, username and password.

Is the data you provided valid/matching that configuration?

Yes, exactly, I copy-paste those values.

A remark, maybe it has an impact… both Coturn and MiroTalk are installed under the same subdomain (visio.mydomain.tld), with Let’s Encrypt certificate.
