Error 522 in Toronto area only

[mario5]

My client site https://www.galganov.com can be accessed from many locations, I’m in Montreal, some people in Florida access it without any problems but my client, in the Toronto area cannot access it. He get’s the 522 error almost every time in the last 24-48h. Sometime the site will load but missing css and slowly loading. He tried on his connection (explorenet) or is phone network (telus) and he gets the same error. I know the origin server is working fine, I even tried turning on developer mode, it didn’t change anything but it started working when I turned off Cloudflare in DNS except we gets security warnings because the ssl on the origin server is not valid.

I think it has to do with the cloud server near that location. Here’s the Ray ID , it might help you figure out why that location is not working.

Error 522 Ray ID: 4e8e26230984ab3a • 2019-06-18 15:03:46 UTC
Connection timed out

Thank you!

I’d make sure Cloudflare IPs are whitelisted, other ideas in this tip, Community Tip - Fixing Error 522: Connection timed out

I communicated with 1and1.ca (ionos) who host the origin site and they claim they do not block anything. Is there a way to get more info on the Ray ID? Something is blocking the request between this particular Cloudflare server and the origin server.

The Cloudflare domain IP is blacklisted in some anti spam but that should only be used for mx, not sure it has anything to do https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3Agalganov.com&run=toolpage#

My client tried a VPN and now he can see the site fine. So it’s really an issue with that particular CF sever

Fixed by now? The Canadian checkpoint at http://sitemeer.com/#https://www.galganov.com can access it fine.
