pfSense webConfigurator does not load on any PC or browser

I've tried multiple browsers on multiple machines & OS's. I have tried the command to restart webConfigurator and rebooted pfSense, but there's no change. I was trying to get a LetsEncrypt SSL cert working (wasn't able to), so I think that's how this issue started. 

I am able to connect via SSH no problem. Any help appreciated. This is for my home lab and routing and everything else works fine, so not an urgent issue. Thank you!
