Proxmox VE is suddenly unreachable

[Keksgeber]

Hi community,

I've got a problem with my proxmox ve. I just can't reach it anymore under its ip-adress (witch is the 192.168.178.2:8006), the curious thing about it is that I've already used it to build a LAMP-system on Debian installed my owncloud and everything worked fine, I even connected to no-ip. But 3 days ago I just could't reach the webinterface or the website.
I don't konw what to do now, pls hep.

well, that for sure is not the ip/port, you should have a typo

maybe it is https://192.168.178:8006 or https://192.168.172:8006 or else
note: https is mandatory, as well as the port, there is no more autoredirection

can you ping that ip address?

Yeah thats really stange. I can ping the IP from my win7 PC

probably the basic networking setup has some errors... more details are needed, and an access to server command line.
can you login to the server, either locally or by ssh (on windows you can use putty)?

Ive had the very same problem about 2 days ago when my proxmox node was abruptly powered off (power outage).. Turned out, the computer I was using to access proxmox was faulty, for whatever reason, the OS was trying to reuse the IP lease that my pfsense VM had issued before the outage..

Proxmox was not at fault, my desktop machine was... Shutdown the machine and rebooted, the IP was flushed and renewed, and all was fine..

Maybe this will help?
