Probably has to do with the way we check the ip before using it in the conf file..
Can you (when you have the time ofc) share output of these two:
hostname -I
and
curl -s https://ip.openpanel.co || wget -qO- https://ip.openpanel.co
and tell me which of those is your router and which one is your local ip?
We can then use the more accurate info for the conf file.
