[SOLVED] Disabled web-interface after upgrading Proxmox

[while1pass]

After upgrading to minor 5.4 version and restarting, proxmox works only by ssh, stopped working gui interface on 8006 port (timeout by curl -vvv https://localhost:8006 https://pastebin.com/0pEt8115) and some hypervisor functions are not available (full list here), example,

root@node-0:~# qm list
ipcc_send_rec[1] failed: Connection refused
ipcc_send_rec[2] failed: Connection refused
ipcc_send_rec[3] failed: Connection refused
Unable to load access control list: Connection refused

also there are a few errors in the logs (pastebin below) but don't understand where to start looking for the problem

example

node-0 pmxcfs[1547]: [main] crit: Unable to get local IP address

or

Nov 08 18:11:27 node-0 systemd[1]: Failed to start The Proxmox VE cluster filesystem.

Many forums advice to check and edit the /etc/hosts file, however, I do not understand how. But maybe my issues don't depend on it.

Fixed issue, it depends on wrong /etc/hosts file, so I edited it according to docs https://pve.proxmox.com/wiki/Instal...d_an_.2Fetc.2Fhosts_entry_for_your_IP_address
set my static IP and hostname to separated line
