Some users (probably from Russia) have err_quic_protocol_error. In the browser and the site does not load. How can this problem be solved?

  Hello,

  These types of errors are typically not generated by the CDN itself. Instead, they are likely related to issues with the user's network or their device setup, such as their PC or browser. Using a VPN might help mitigate the problem.

  I have same problems (Chrome, Canada). Some users on website has same problem. I just moved domain from Cloudflare where a similar error hasn't occurred. Is it possible that the problem could be related to the settings in the Gcore panel or the SSL certificate?

  Hello,

  We have rechecked the issue, and the reason is that QUIC (HTTP/3) is not activated by default. We can activate it by request but only for paid tariff plans. Unfortunately, it's not possible to configure on a free plan.
