hello, that certificate isn't valid for subdomains: https://www.ssllabs.com/ssltest/analyze.html?d=ans.e-dnk.ru&ignoreMismatch=on&latest this would need to be fixed by the site's owner...

Thank you. I know, that certificate isn't valid for subdomains, but I don't why server sends this certificate for subdomains and why I haven't this trouble in another browser.

sorry, we cannot answer for other browser vendors, why they wouldn't show a warning on the site with a certificate that is obviously a mismatch...
