Nextcloud HPB/Coturn setup not working

What app is this about, and its version: Coturn 4.6.1.1~ynh2, Nextcloud 33.0.1~ynh1
What YunoHost version are you running: 12.1.39 stable
What type of hardware are you using: Old laptop or computer

Describe your issue

Coturn is “Not reachable?” when checking trickle Ice test. The error logs for the cotrun service says credentials not found for the user

I was using nextcloud without the high performance backend but it kept throwing a warning when starting calls so I thought I’d set it up. But I’m stuck here and there are only old posts with no replies, please help.

How did you configure your credentials in the Nextcloud Talk ?

I have parameters like this

Server STUN :
turn.domain.tld:443

Server TURN :
turn.domain.tld:5351 (port found with grep port_turnserver_tls /etc/yunohost/apps/coturn/settings.yml)
secret (found with grep turnserver_pwd /etc/yunohost/apps/coturn/settings.yml)
udp and tcp

I hadn’t gotten to that part yet since the coturn test is failing. The logs just keep saying the same thing. Is it something like I have to add it to nextcloud first for it to start working?
