When you tested your domain using the [Cloudflare Diagnostic Center], what were the results?
Looks like this appears to redirect to support center, instead of any such tool.

Describe the issue you are having:
I have 2 top level domains registered with Cloudflare, one domain, along with a number of subdomains is pointed to my home’s ip and proxying various ports. This is working perfectly fine. However, my 2nd domain, I am trying to set an A record for @ (root A), to the same IP and it is returning a 522 when proxy enabled. As a test, I stopped my webserver, the first domain returns fast an expected host down message (as a result of connection refused to 443), while ne8 hangs for a while, and times out with 522 still. The domain works fine if proxy is turned off, however I would like the proxy on. I also ran packet captures at my WAN, and see NO ip’s reaching me at 443 for ne8, but for my other domain I do see various packets (tcp) at port 443. This eliminates firewall issues, or anything with the web server. This seems to be something internal to Cloudflare, where it does not want to connect to my ip from the ne8 domain. Also just a note, this domain was recently transferred to Cloudflare from another registrar (couple days ago)

What error message or number are you receiving?

What steps have you taken to resolve the issue?

  1. Toggled Proxy multiple times
  2. Packet catpure at WAN interface of ip, verifying no firewall rules blocking Cloudflare
  3. Webserver configuration keepalive verification (which is fine, because other domain to same ip works)
    4 Webserver log verification (nothing reaching web server)

Was the site working with SSL prior to adding it to Cloudflare?

What are the steps to reproduce the error:

  1. Visit ne8 dot org (domain link at top) port 443 in web browser
  2. See 522 Error

Have you tried from another browser and/or incognito mode?

I am willing to try anything at this point, I do have intermediate experience with networking, software development. Also, sorry with the various dot instead of . etc, forum not allowing me to have more than 4 links.

Anyone have any ideas on how to help here?

Not sure how or why, but using a origin certificate and switching to Strict under ssl settings fixed this issue. It must have reset something on Cloudflare’s end, as I was receiving no traffic to 443 earlier.
