CloudFlare reporting 522 from various regions

Some of my domains, all of which point to the same origin, are reporting 522. If I bypass Cloudflare entirely and route the DNS directly to the origin server all regions are able to access the sites.

As of this writing https://www.clanaod.net works and https://clanaod.net does not from several location in the US (a VPN to Europe seems to avoid the issue). I presently have a rule bypassing all Cloudflare asset caching because of other regional issues (with the rule removed, the Netherlands report 522 errors) so I’m just using Cloudflare as a proxy/ddos protection.

Please help.

Both work for me from the US. A 522 error typically happens when Cloudflare requests to the origin (your webserver) get blocked. If it comes up again or if you’re still having issues, review the suggestions in this Community Tip for troubleshooting ideas.

We do not implement any IP filtering or rate limiting nor does the host for the server. I’ve already checked with the provider and they are not reporting any current issues.

For https://www.clanaod.net/ visiting the site and on shotsherpa I don’t see an error, https://shotsherpa.com/adventure/5d425d7f51a54007b63b50f3

For custom locations on shotsherpa, including two in Netherlands, I see a 522 in Dar es Salaam, https://shotsherpa.com/adventure/5d425e0a51a5400832649e63

For https://clanaod.net/, I’m seeing 522 with Asheville & Dar es Salaam, an upload error for Fez, https://shotsherpa.com/adventure/5d42604551a5400a5318ff72. On a random test all is ok, https://shotsherpa.com/adventure/5d4260fb51a5400ae7010b87.

Support may be able to help you trace this down a bit. When you contact them, at some point they’ll ask you to give them an MTR or traceroute from your origin web server to a Cloudflare IP address that most commonly connected to your origin web server before the issue occurred. Identify a connecting Cloudflare IP recorded in the origin web server logs. And, they’ll ask if you can share the details from the hosting provider’s investigation such as pertinent logs or conversations. After you contact them and receive a number, share it here and reply back to the ticket with a link this thread.
