Hi, first time setting up a subdomain that is proxied to a service running directly on my server.
Every time I try to connect to it, it fails and Cloudflare returns me with a 522, however, I'm not sure why it's returning this.
My server isn't overloaded (as far as I could tell) and the app is running in Docker with the service started at the standard HTTP port, and I confirmed it was running by directly access the IP it was assigned and confirming I got a proper site back.
How would I go about investigating/fixing this issue?
