Can access all the VMs via WebGUI, However ssh isn't working for a majority of the VMs

Hello Proxmox forum,
I am a newbie in using Proxmox and got a old system from a friend. Now, suddenly majority of my VMs cannot be accessible via ssh. However, I can access all the VMs from the WebGUI.
Any pointers is much appreciated.

Usually it's a firewall issue, try using pve-firewall stop (wiki) to temporarily disable firewall and then try connecting to these VMs again
