Hello,

I am using Proxmox 8.3.3. and after a reboot I cannot access GUI, cannot ping proxmox or any VM (VMs are not online as well). I can reach proxmox server over SSH anr Winscp.

There are no errors (I went through previous threads on this subject and all rights to folder and certificates are ok, haven't found anything, logs are OK, services are running), even when I turn off the firewall i still cannot access GUI. the service is running. E.g. curl command returns html. I cannot ping the machine except from servers on the same chassis (we use Supermicro with 8 blades. I can ping it from another blade but not from other computers in the network - and vice versa works ok).

The interfaces file looks ok. Any suggestions?

Thank you
 
I found out what was the problem. The firewalld turned on after reboot. I was looking at other "firewalls" but not that one therefore this caused the issue. After disabling it is all back to normal. Have to remove it now for good.
