Placed new certificate into Firewall webgui no longer available

[basqueman]

Hello,
Yes, I am a N00b.  I placed my own generated cert into the opnsense and now the WebGUI is no longer available.  I can access the firewall via SSH and all traffic is flowing, but I can no longer access the firewall via the WebGUI.  Is there a way to fix it without rebuilding ??  Thanks

When logged into console, go to settings history, and select a previous setting.  Try each one till you are able to access the gui.
