Error 522 from Russia


The website does not load resources properly from Russia using Cloudflare. Part of resources are hang. Sometimes it took 5-6 seconds. For instance, TTFB 15.6 sec and HTTP status 522.

However it load fine from other regions(UK, USA). Also exactly the same website load fine using direct link by passing cloudflare. We tried differernt source Ip address from Russia, seems the issue is for the whole Saint-Petersburg. Might be there any issue with Cloudflare relays specifically for Russia? Thanks

Lets start with the output of

Also, did you check out Community Tip - Fixing Error 522: Connection timed out?

uag=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.129 Safari/537.36

And the link?

Sorry, link to what?

The link I posted.

I read the link above none of the quick fix idea can help me. Hosting provider is not blocking cf. Other websites (not based on cf) works fine, hence hosting provider does not have any issues with infra. It does not work properly ONLY for CF and ONLY for 1 specifc region, tried from different clients machine.

Moreover it is not completely blocked, sometimes it works, sometimes it took a lot of time. Some of the requests randomly fail

That does sound very much like #3 in that article. If your provider insists they do not block anything, you can only try to open a support ticket with Cloudflare and maybe they can tell more, but usually this is some kind of block on the host’s side.
