Opnsense in proxmox, cannot be reached

[Gargamel]

Until just a little while ago, i could access the opnsense interface (port 443).
Made some changes to dhcp leases, each page load took many many seconds, looking in the pve of proxmox interface, all the sudden all cpu died/stopped.

I have tried rebooting the whole server. opnsense boots and looks normal thru proxmox console, but nothing can ping opnsense, web admin pages does not open
opnsense has 2 interfaces, one is a public ipv4, and one is lan 192.168.1.1, nothing else that is on the lan vmbr1 can ping opnsense.

Any ideas what more i can check why all the sudden everything opnsense stopped working? No network related settings has been changed the past day or two and it worked up until perhaps an hour ago.

EDIT: I tried re-set ip for lan and changed to HTTP, still doesn't open nor do dhcp work for lan devices.

If you can still get to OPN via the Proxmox console, then I would start diagnosing from there. Check logs and verify the interface settings.
