Yesterday night I noticed my HAOS server was down, weird. I hadn't used it or done any changes. Browser didn't load, observer didn't load. Ping worked, host was ON. Plugged HDMI, and there were tons of errors.
Left it for this morning, rebooted host, it happened again. After a 2nd reboot, it booted fine and HA was accessible. It has worked for 1h or so, and now I've noticed plenty errors again. It's still accessible, but lots of things not working. Seems like a host level issue, but I can't decipher the logs.
