i'm using adguard and firefox. when i try to connect to certain pages(ex. Adguard Homepage), firefox says the connection is insecure. How can i solve this problem? i've already tried reinstalling certificate and manually importing it.

Which certificate is shown for these sites and which exact websites are those?

Adguard certificate is shown for the sites and I can't see what they have in common. The sites I know are https://adguard.com/ko/welcome.html, https://forum.adguard.com/index.php, https://www.cloudflare.com/ssl/encrypted-sni/, https://blog.cloudflare.com/.
I think this problem is related to esni. When I disable esni or Adguard, there is no problem.
But while both are enabled, I can still connect to the sites after a lot of refresh tries. In this case, Another certificate is shown instead of Adguard certificate.

Hello Gentlemens!
It seems that we are talking about this problem. It is already known to the developers and they will try to fix it in the near future.
