Issue Details

Steps to reproduce:

1. Go to https://formula1.com
2. In the browser assistant popup, check the lock icon next to the URL
3. "HTTPS filter was not performed" or "Could not verify this website's certificate"

Expected Behavior

The certificate seems fine and is not expired when I check it myself so I would expect that AdGuard performs filtering

Actual Behavior

AdGuard thinks for some reason that the certificate is expired and doesn't filter this website

Hi @SebastianRasch

Please try to update to the latest version of AdGuard for Mac which is v2.13. This issue should be fixed in this version. Please let us know if you still experience this issue with v2.13 installed.

Thanks @AlexandrPkhm, now it's working perfectly on 2.13!
