WordPress site is connected via cloudflare cloudflare is configured like this: SSL - Full (strict) enabled wp plugin “Cloudflare”
I get error 522 (connection timed out) through my ANY mobile browser in my smartfon (use 4g internet conection, Megafon-Moscow, Russia).
But if enable VPN application, connection available! From home PC too all good.
how is this explained?
Most likely, the host is blocking the IP address of the Cloudflare edge node that’s trying to connect through Megafon’s route. From your 4G phone, can you connect to example.com/cdn-cgi/trace (but use your site’s hostname) and let us know which “colo” it says?
And do the same with your VPN and home PC as well.

Ok, then that’s most likely it. The host is blocking some of these addresses: IP Ranges
What do you mean by “host”? Mobile service provider?
Of the website.
ok. thanks!
Only I do not understand how this is possible.
Why, then, is the site available from other IP addresses?
cloudflare addresses the host at different ip addresses, depending on some client connection parameters?
