Hi all,

I was working on my vms and All was good...
After a pause, i'm wanting to connect again to my proxmox server and :
- i can connect but i don't have cluster in my database where i have all my vms
-I can't connect at all to my webgui proxmox with "Connection failure. Network error or Proxmox VE services not running?"

I tried to restart some things that i found like systemctl restart corosync but i have an error :
Active: inactive (dead)
Condition: start condition failed at Sat 2022-03-19 21:51:09 CET; 8s ago

Ok, i'm connected to the web interface but i don't see my cluster or my node with my storage and my vms.

It said server offline
 
i'd like to change the name of my server (physic server) and i changed it in /etc/hosts. (i didn't have access to my node before i did that)
It's why i can't have access anymore to webgui but i can't find why i don't have my node with all my vms in my datacenter.

I'm trying to find...
 
My vms are working. I can start them manually by ssh : like qm start 105

How can i get my cluster (only one cluster) running again and appeared again in webui ?

My node is there but not shown in the web interface with a connection error :

Ok, solved again...

I just deleted all cache with :
ctrl + shift + delete and, it's back again :)
