hello, I have been running proxmox on-premises for my company for just little over a year and I have this issue happens after I move the servers to another office location. Everything is working fine for few days after office moving then proxmox starting to become un-responsive, first I tried rebooting, then It just resolve itself eventually then the rebooting trick stopped working as well(It still works I think but seems to be requiring luck, but now 90% of the time does not work), I tried checking `pve-cluster`, `pvedaemon`, `pveproxy` and `corosync` those services look fine on all node sometime, sometime `pveproxy` shows `client problem, connection reset by peer` but networking seems fine and no firewall seems to be blocking, I can reach the proxmox web ui but not able to login, it just hanging there after enter the credential and timeout eventually and running `pvecm updatecerts -f` always result in `got timeout`.
The new office location already have networking setup, so the proxmox servers just connecting to another vlan with same ip cidr, ssh between each proxmox nodes is working fine, when proxmox is working, communication between nodes and each vm itself also fine, I can also access to services within vm from outside using public ip fine, except I notice an issue, all vm created within promox before now has wrong default route, eventhou I check the config from `/etc/network/interfaces` it looks like it is correct but vm gets the wrong one but I add the default route in manually afterward and it solve the issues but anyway those are issue that I notice after moving to new office which before does not happened.
so currently I am not sure how to debug and fix this issue so I any advice would be appreciated, and thanks for your time reading this.
