I am currently trying to fix an issue I am having with my reverse proxy for my node instance that I would like to be publicly accessible. (I haven't fixed it yet) However in one attempt to make sure all things were covered I disabled my firewall.
I then, enabled it again... And now, navigating to any site on my server results in beautiful 503!! https://warhammer.hutber.com/
I have to say, my knowledge is simple, check if its Listening... make it listen if it is not. So now I am just plain confused as to why none of my sites are working or what it could be.

The only other things that I can think might have possible affected... even though I am 99% sure after making each of these changes I did check and saw my graphql endpoint was still not accessible. I reset the apache2 service after each of these... so I only have 1% fear!
