Coturn Not reachable? Check_stun_auth: Cannot find credentials of user

andreiu · October 12, 2025, 9:23am

What app is this about, and its version: coturn 4.6.1.1~ynh1
What YunoHost version are you running: 12.1.27
What type of hardware are you using: Old laptop or computer

Incorrect description of the coturn app

The coturn app states the following:

For testing, we can use the Trickle-Ice testing tool. Go to the trickle-ice page and enter the following details.
STUN or TURN URI: turn:ustincloud.ru:5349
TURN username: turnserver
TURN password: secret key

However, coturn itself is configured by default for static-auth-secret authentication, which uses only one secret key (without a login).
When attempting to test via the trickle-ice page with the provided login-password pair, it returns “Not reachable?”, and coturn itself returns the error “check_stun_auth: Cannot find credentials of user”
Accordingly, using this login-password pair in conduit calls will not work.
The coturn app description needs to be corrected.

TURN username:    turnserver

Sorry you explain it just before…

With static-auth-secret there is no login, only key. If use user “turnserver” with this key in default settings coturn, it gives an error “Check_stun_auth: Cannot find credentials of user turnserver”.
