It would be super-useful if there were an option to use an external turn server instead of the Cloudron one. Since our server sits behind a Cloudflare proxy, the Cloudron turn doesn't work out-of-the-box. It can be made to work on an app-by-app basis by changing the turn server address from turn.example.com to the real IP address or by using an external turn server. But neither option is persistent, getting overwritten each time there is an app restart. So an option to set the preferred turn server would be super-helpful to avoid having to do this manually each time.

Add External Turn Server
RE: Add External Turn Server
This is your case, not everyone is using Cloudflare.
Indeed, I know that this is specific to my case and that not everyone uses something like Cloudflare. But it is a big player, so worth addressing. As I say, it can be worked around and still use the Cloudron turn by using the real IP instead of the domain name in turn configs. But that gets overwritten, and an option to use external turn server would, frankly, be very helpful indeed given some of the other challenges with the Cloudron turn server that you highlight.
[By the way, and not related to my specific request, I will say, that I have had fits in the past trying to get the BigBlueButton's suggested turnserver configuration working and really have found the whole 443 setup to be too difficult. So even for our BigBlueButton server, we've just ended up using an external turn server running on 3478 and 5349. The challenge I think is that the turn server monopolizes 443]
RE: Lessons learned (Updating to version 22.0.0)
@luckow Same here. Caused a bit of a scare I must say. But indeed can be fixed as you say.
The other thing with Nextcloud 22.0.0 is that creating new groups has been broken. And for some reason groups created with the workaround that is there (writing in a new group in a user's group profile) means that groups cannot be seen in the calendar app (e.g. to attach groups to the shared calendar). Apparently there is a fix in Nextcloud 22.0.1.
Kind of is what it is with Nextcloud, sadly...
