Comment:

Cloudflare verification consistently fails when using a private AdGuard DNS server. The website displays the following message:

ksp.co.il
Verifying you are human. This may take a few seconds.
Verification is taking longer than expected. Check your Internet connection and refresh the page if the issue persists.

Refreshing the page does not resolve the issue. The problem disappears when AdGuard DNS is disabled.

I turned off all AdGuard DNS filters, but the issue persists.

However, when I disable AdGuard DNS entirely from the system settings, the problem is resolved immediately.
