Hello,
everything worked fine until i wanted to change the network adapter.
My OnBoard LAN is the new Intel I219 NIC. For the installation I used another Intel NIC (a pretty old one) and installed the latest backport kernel.
Now I am not able access the webinterface anymore.
I also tried to switch back to the other NIC but it doesn`t work either.
Everything else ist working (SSH, Plex, Teamspeak ...) perfectly without any issues.
I got the following problem:
After er restart the Server i can access the web interface and I am also able to log in. But after a few seconds it is loading and loading and loading. After a minute I get pop up messages like "connection fauliure" and I cant access the interface anymore. If I reload the page I usually get a simple error message "network timeout". But sometimes I also get the message "Error 504 - Gateway timed-out ... nginx"
I cant make any changes in the web gui. After I want to apply a change the web gui is loading endless again.
Firewall is disabled btw.
