Unable to connect to HA

So today, I did a HA server restart after adding a component and I couldn’t get back in. I added a zone and needed to restart the server but it never came back.

I got to the UI login panel, but that’s it… I typed in password and after a while it says Unable to connect.

I looked at a the log file and nothing jumps out at me… everything looks normal… no specific error, exception there was no activities going through the logs…

I do not know what to do or what to check… any one ever experienced something like that and how to resolve it?

Never mind… after an hour… and multiple reboot and restart… it came back on… right after I submitted this entry :frowning: so sorry… I was a bit paranoid when it happened. I removed the zone…
