Proxmox PVE 2 hang after soem time.

Hi ,, the headiing is a bit missleading :)

When I have my browser up running and using proxmox PVE2.xx it works fine.. It sometimes natually times out..

Now I have had the following experienc etwo days on a row that when I try to access teh PVE 2 panel that I am not able to get up the login page.

I know the Proxmox runs fine because webpages are running fine.. ( I guess so)

So teh milliion dollar question is why is this happening?
I have tried to log in with several browsers but no luck..

THxs
