Timeout https connections in Russia

A problem with the inability to access the domain hgcdn.ru and cds.hgcdn.ru via https from some regions of Russia (Moscow) has been detected.
From other countries everything works as it should.

Sometimes the connection goes through, but most often there is a timeout.

Timeout exactly to the Cloudflare server because even the Cloudflare stub is not loaded.
Is there a way to solve this problem?

What IP address are those domains resolving to for you?

It sounds similar to is not responding ru Russia connections


Yes, they both do not responding.

Port 443 is blocked for,,, addresses on RU TSPU (ТСПУ) hardware — a government-made censorship black box installed on many, but not all residential ISP networks.

Use another DNS resolver

The blocked IP addresses are used for many domains are a part of geobalanced IP set. Most often this set is served over Google DNS (regardless of EDNS Client Subnet).

Switching to Cloudflare’s resolver may help, or at least will decrease the probability to hit these addresses.

Add another non-blocked IP address for domain to hosts file

Cloudflare’s balancer allows to use almost any IP address for any hosted domain. Thus, it’s possible to use any non-blocked IP address of Cloudflare to access the website.
Add something like this to the hosts file: hgcdn.ru cds.hgcdn.ru
