Webgui does not load even though DHCP lease attained from LAN port

[Medicineman25]

I have a very strange issue occuring where the webgui will not load.

Initially I was using a static ip on my machine @ 192.168.1.20 to access the gui. I did access the gui and had a look around, I added some firewall rules but then turned them off. Then I changed the WAN interface ip address to a static ip @ 10.x.x.x range and now everything seems to have broken.

What's odd is the dhcp server on the LAN port is up and served me a dhcp lease without any trouble, and nmap shows ports 80 and 443 open on the machine. However, as the title states, the webgui simply will not load.

I have tried multiple browsers and clearing caches, nothing seems to work. Also worth noting is the error message, it times out instead of just not being able to find a machine at that ip address. I tested this by trying to access known blank addresses and getting a different result to the opnsense machine.
