Proxmox cannot ping a server in the network yet the rest of that network

Hello Experts,

There is a weird situation with proxmox.

I cannot ping from proxmox a server in the network yet the rest of network I can.

The actual virtual machine can ping the server.

The server we want to ping is the primary DNS server (if it makes a difference).

No idea where to begin troubleshooting.

Yes, you are right. I just started here and I am new to proxmox.

Let me keep digging any useful detail.
Well according to someone here.

He said that it will be helpful that the proxmox machines ping the multi-cast address:
