I've had OMV2 running on Debian for about 6 months now with very few issues. A week or two ago I tried to access the WebGUI from another computer on the same LAN and wasn't able to find it. Since then I have never been able to connect to the WebGUI. Entering the IP that is assigned to it just comes up with a "This page does not exist" message.
I can tell OMV is still running though as SMB still works, and within the machine itself Emby and Snapraid still function perfectly fine. All of those were also set up within OMV using the plugins.
Since this a supermicro build there also is a second NIC which I can use to remote in using IPMI. That still functions properly as well.
Does anyone have any ideas as to what might be going on? I changed nothing within the software or hardware and it just became inaccessible out of nowhere.
