Intro to Error 522:
I am attempting to host a website from my man-cave. It had been out of commission during fall semester, but now I have rebuilt the site and re-enabled dynamic dns, I am getting the 522 error. The setup is exactly the same from what I can tell. The only difference is that instead of updating my ip with dynamic dns on my router, I am now updating it from the actual server that is hosting the site, and it is updating it correctly.
Enabled keepalive and extended the keepalive_timeout to 135 secs on the host server.
Whitelisted all of Cloudflare’s ip network ranges in my firewall configuration.
Stopped and disabled all other unnecessary processes on the server that could possibly put additional strain on the system.
Checked all of my firewall policies on both firewalls.
Ran traceroute from the source server.
Checked that the dynamic dns is updating correctly.
The only potential issue is that one of the external network hops drops a lot of packages. It belongs to telephonica.com, which is not even in the same country as me.
I am running out of ideas. Anyone have any suggestions?
