I did man, completely removed it using "plugin remove" command.
Didn't do anything
Yeah from another computer or any device the webgui was unreachable, using "servername.local" and also the IP address directly unless i boot the server up in safemode with no plugins, only then i could reach the webgui from other devices.
I actually re-downloaded the nvidia plugin whist in safemode, so i could get plex up and running.
The next day I bought unraid plus and upgraded the key, and I restarted to test 1 more time before beginning the process of disabling plugins, 1 by 1... thankfully it just worked.
