How to reload coturn when ssl certificates are renewed? about coturn HOT 1 OPEN

Hi,
if you're using certbot in a script you could just add systemctl restart coturn.service at the end of said script. From my experience you can restart the service even if you have connections, since a client will build a connection again once the old one is dropped. The restart takes only a fraction of a second.
If you're using coturn as a docker container then it could get more complicated, but is still doable since you "only" restart a docker container (docker container restart coturn), or, to be safe kill the container and create a new one. This will load the new certs.
If you really don't want any downtime you should do these steps when there's little or no traffic (nightime) using crontab.
Hope this helps.
Regards,
J.
