Just got done updating my OMV server to version 4. Most things seems to work, but I have lost the ability to connect to my server from the outside.
I've done NGinx reverse proxy in 3.x which is still there in 4.x (and restarting Nginx produces no errors).
I can also reach everything from my local network, I can reach the domains too (example.com), not only local adresses.
But this only works when I am connected to the same network.
As soon as I get outside the network the domains are unreachable.
Can this have something to do with Let's Encrypt? Do I need to renew the cert for 4.x?
I have not made any other changes from 3.x where it was all working good!
