Hi all!
It's my first try with Proxmox and Opnsense.
In the console i get the message to access the web interface via https://192.168.1.101, but this address doesn't load anything
console - option 11 - restart all services.
Try restart and access https again.
There was similar issue here (resolved already I think):
