Not connectivity to Proxmox host via local subnet but other subnet works

[VioSpeed]

Hey guys,

All of a sudden I can no longer access my Proxmox host via the Web GUI and SSH, it's also not responding to pings from any device on the same subnet. I do however have full connectivty if I access it from another subnet even when I'm offsite via a VPN. All the VMs on the same host are accessible via the local subnet.

Does anyone know what would be causing the issue?
