This issue crops up every now and then for me, and seems to be aggravated when I run multiple VM's. My unRAID server totally locks up and I get disconnected from RDP sessions to my VM's. The WebUI becomes inaccessible (timeout on port 80) SSH is refused: ssh: connect to host 192.168.1.212 port 22: Connection refused Something seems to be alive though since I can still ping the IP, and a port scan shows multiple ports up. % nmap 192.168.1.212 Starting Nmap 7.99 ( https://nmap.org ) at 2026-05-06 21:41 +0200 Nmap scan report for 192.168.1.212 Host is up (0.034s latency).

Connected to 192.168.1.212. Escape character is '^]'. GET / HTTP/1.0 ^C^] telnet> quit If I try login locally via the console, I enter my username but can't get to the password prompt. I get a 60 second timeout and dropped back to the login prompt. The only fix is a hard reboot, to which I can then access my system for a while until this happens again. I have no idea how I'd even approach diagnosing this, i've tried a clean install, wiping my flash and restoring the license as if it were a new install. I run this on an intel nuc i7 10th gen, and at this rate I think the hardware is just not a good fit for unRAID. Anyone have any ideas?
