Why Legitimate Russian Websites Fail to Load With or Without VPN: TSPU RKN Blocking and MinTsifry Certificates Explained
Russian internet users are experiencing widespread access issues to legitimate domestic websites both when using VPNs and when connecting directly. The problems stem from TSPU devices installed by all ISPs under Roskomnadzor requirements and the transition to national MinTsifry certificates that foreign browsers do not trust. Three distinct error scenarios are documented: ERR_CONNECTION_TIMED_OUT when accessing Russian-IP sites over VPN, ERR_CERT_AUTHORITY_INVALID on major bank sites without VPN, and partial page loading failures caused by TSPU fingerprinting. Solutions for ordinary users include split-tunneling VPN clients, installing MinTsifry root certificates, or switching to Yandex Browser and Chromium-Gost. Website owners are advised to disable TLS 1.3, enable HTTP/2 support, and consider changing server IP addresses if SSH connections are also blocked. The article explicitly excludes any discussion of circumvention methods for prohibited content and focuses only on legal Russian resources as of August 2026.
