as said, there's no real problem right now, still I don't understand the behaviour and am curious.
you're talking about accessing the Cloudron through entering the IP (192.168.x.y) in the browser?
It's clear that this wouldn't work and this is not what I'm doing, it's a little more complicated:
the PC I'm accessing from, is in the same network segment than the cloudron (192.168.x.z).
OpenVPN is active, the OpenVPN service is on a second cloudron outside in the internet
still, when entering the URL (https://my.domain.*), the fritzbox page shows
as soon as I connect the PC to a different network segment (192.168.y.z) everything works!
I don't understand why. Shouldn't the use of external VPN service make the internal source IP invisible?
wordwrap!!! the problem was staring me in the face! But I could not see it because i did not scroll to the right...
Thanks for the help!!!!
I took a cert and key file from another server, and renamed the default cert to be whatever the error wanted.
first thedomain.com.cert, then thedomain.com.key. and so-forth until it loaded. It is working now! .
