Many users and developers in Russia experience sudden issues with accessing standard, legitimate websites. As of August 22, 2026, the use of circumvention tools is not officially prohibited in the country, but specific network filtering mechanisms can disrupt connection stability. Understanding the root causes of these failures helps to configure operating systems and software correctly.
How technical traffic filtering tools impact connectivity
The primary reason for these network issues is the deployment of TSPU—specialized technical threat mitigation systems installed on ISP networks. This hardware analyzes all passing traffic to restrict forbidden content and limit unwanted services. Consequently, completely legitimate resources may occasionally become unavailable to end users.
Why pages fail to load with active encrypted connections
The first common scenario occurs when trying to access a Russian resource with an active encrypted connection results in a timeout error (ERR_CONNECTION_TIMED_OUT). This happens because traffic filtering systems often block incoming foreign requests directed at Russian IP addresses. However, if a domestic resource, such as ruvds.com, uses a foreign IP address, it will open without any issues.
To resolve this issue, you can configure split tunneling in your client settings, routing traffic to .ru, .рф, and .su domains directly. Alternatively, you can temporarily disable the connection for specific sites or separate your application usage, running one browser with active tunneling and another for direct connections to local portals.
Untrusted security certificate errors in web browsers
Another scenario involves invalid certificate authority errors when circumvention tools are turned off. Visitors to major Russian financial websites, such as Sberbank, VTB, Alfa-Bank, or Promsvyazbank, frequently encounter this. The issue stems from these platforms switching to domestic SSL certificates from the Ministry of Digital Development after foreign ones were revoked, whereas global browsers do not trust them by default.
To bypass this security warning, you can navigate to the browser's advanced settings and proceed to the site. In trickier cases where the HSTS mechanism prevents this, entering the special service command "thisisunsafe" in Chromium-based browsers can help. For a permanent solution, consider using Yandex Browser, Atom, or Chromium-Gost, or manually install the Ministry of Digital Development root certificates into your operating system.
Actionable advice for website administrators and owners
If you are a website owner and your visitors report connectivity issues, disabling TLS 1.3 and enabling HTTP/2 support can resolve the problem. If these measures fail, consider changing your server's IP address via your hosting provider. Newly created virtual private servers often receive addresses that are already restricted by filtering systems, preventing even SSH connections.
With the HiroVPN service, users are protected from such connectivity issues and can reliably access necessary resources without constantly adjusting their system settings.
