IPv4 stopped working, IPv6 works

[xebec]

I am having a problem where after an update, I lost all IPv4 connectivity. IPv6 thought works

This is my setup:
1. Running proxmox on a mini PC (Virtual Environment 8.1.11)
2. Network layout
Pfsense (router) --> Unifi Switch --> Proxmox MiniPC (172.25.90.50)
3. Proxmox server is on its own VLAN

These are the outputs (IPv6 address redacted)

Nothing on the pfsense firewall side of things had changed, and I cleared the state table just to be sure. I also turned off snort to diagnose.
I also cannot ping the proxmox address 172.25.90.50 from my laptop or from the pfsense interface for the VLAN

It's not a VLAN issue (since IPv6 is working)
The ethernet port is working (since IPv6 is working)
Gateway and subnet is correct (nothing changed)

What could I possibly check?
