Problem with audio-video calls (STUN USER)

[susobaco]

Hello, I have been testing audio or video calls and I have observed that they are performed well from the browser:

79: : session 001000000000000004: delete: realm=<*********.org>, username=<1686138035>

But, when making them from an external client, (Dino or Conversations) there is an error at the time of authentication on the STUN server, the user is missing.

turnserver[578]: 257: : session 000000000000000016: realm <*************.org> user <>: incoming packet message processed, error 401: Unauthorized

Could this be due to a registration problem of this program?
