turn server config
switches from 
to this

and stays
Question1β
am i missing something or is ist supposed to be like this ?
turn server and nextcloud are on the same server
10.10.10.30
logfiles look like that
Question2β i got no idea where/why the 401 is caused
config like this
Looks the same for me, before clicking on the βmonitoringβ icon.
After clicking on it, it checks the connection, and tells you with the check mark that all is fine, afterwards it flips back to the monitoring icon.
So you should be fine as long as you followed the official documentation
https://nextcloud-talk.readthedocs.io/en/latest/TURN/
And based on your second screenshot with the config
- you should not share your secret
- your
static-auth-secret
should only be mentioned once in the config, otherwise the last parameter replaces the previous ones.
