Cloudmin backup server down

My backup server seems to indicate status as down.

I can SSH into it (its a local server at home) and also can access through nomal web access for Cloudmin/Virtualmin.

I use it for doing backup and backup has stopped working, I think its due to some SSH problem,

SSH is working as normal

anybody any suggestions where to look ?



I think its down to some network problem blocking port 22
so I am investigating

it was working up until just afte rmidnight last night
