So, here's the basics of my system:
OMV 4 installed on SSD in a PC with 8GB RAM, 3 internal HDDs & 3 USB drives connected. Up to today, working perfectly, used as a file vault, PLEX server, pihole.
It has a static IP address and when I scan the network I can see it. It responds to ping requests with zero packet loss. I scanned it for open ports and the only open port is 111 ( sunrpc ), so no http, no ssh or other ports open for Plex etc.
I have no clue why this has happened. The only thing that it could be is something is cooked inside maybe as it's in a hot environment. I'll have to use a live linux boot disk to see what's what.
Any ideas anyone? Struggling here, thanks!
