I’ve been running HA OS on proxmox for a couple of months, the Home Assistant Cloud connection has worked fine…until now
Obviously something I changed on my end has messed it up - otherwise there would be multi-posts about this 
I was wondering what others have done to investigate connection issues to the authentication server, or cloud in general - maybe there’s an generic, ordered set of checks to help narrow down/eliminate where the problem comes from?
Cheers
John
PS I haven’t mentioned what I tried already - you will almost certainly have a smarter take on it than I had…
PPS I rustled up a raspi with hassio installed and that worked fine seeing cloud, this is a specific machine issue then
