(Hyper V) Can ping and curl but not access webGUI for pfSense. Please help T_T

I set up pfSense (CE version 2.7.0 iso) on the Hyper V for my 2019 windows server but I cannot access the WEB configurator (first time setup). I am trying to set pfSense as a firewall between the WAN (192.168.32.16) and the internal LAN (172.28.240.100). The pfSense setup has the WAN inteface set as v4/DHCP4: 192.168.32.22/24 and LAN interface set as v4: 172.28.240.2/24. I can ping pfSense's LAN from the server and even do curl. I can also ping the server's LAN - vEthernet (nat) - from pfSense.

I tried to access both http://172.28.240.2 and https://172.28.240.2 but neither worked. I can ping 8.8.8.8 from pfSense so I know the WAN interface works. I am pretty sure I am screwing up somewhere in the LAN setup. I am very lost at this point. I have tried disabling any default firewall rules by running pfctl -d and I have also disabled the Windows Defender Firewall for testing purpose. I still cannot access the WEB GUI. Any help would be appreciated. Thanks

The ipconfig for my server is:
