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.
