Turnserver cannot start because private key file is not set properly

Hello,
I’m running jitsi-meet on debian 10 and after an update of ‘coturn’ from 4.5.1.1-1.1 to 4.5.1.1-1.1+deb10u1), I have these errors in syslog

In this system, I’m using valid TLS certificates managed by certbot. Shall I use that one instead of those by default in /etc/turnserver.conf ?

cert=/etc/jitsi/meet/meet.cmnog.cm.crt
pkey=/etc/jitsi/meet/meet.cmnog.cm.key

Tip: coturn + certbot issue on Debian Buster

thanks for the tip. I have used the hook script.

But I add two issues. The second is the binding to port 443. I decided to use the listening-port provided in /usr/share/jitsi-meet-turnserver/turnserver.conf (4446).
So far, turnserver is not complaining but I’m pretty sure I would have to adjust jitsi-meet settings later on

turnserver tries to listen TCP/443 but probably the web server (nginx) listens this port and turnserver can’t bind it.

I just noticed this update in jitsi-meet code today . Hopefully it will avoid this issue on the next stable release
