The site works fine when disabling DNS protection or adguard entirely

Reproduced only with AdGuard for Mac or AdGuard DNS.
Not reproduced with AdGuard VPN app with Cloudflare or AdGuard DNS.

@KibosJ Cannot reproduce on AdGuard for Mac 2.15.1, can you try this release?

[KibosJ]

Still occurs on 2.15.1 for me.

@KibosJ Please show ping civilservicejobs.service.gov.uk and nslookup civilservicejobs.service.gov.uk output.
Does it happen when used another server (Google) in AdGuard settings?

Changed DNS to Google and a few others and it still doesn't work.

Disabling DNS protection doesn't seem to work anymore either, I can only get it work by disabling adguard altogether.

[KibosJ]

I noticed in the filter log that it showed this:

I disabled the Protect from DPI option and the site works fine, re-enabling this option stops it from working again.

@KibosJ As a workaround, you may add rule @@||gov.uk^$stealth=dpi to add Anti-DPI exclusion for gov.uk

[Alex-302]

Added @@||civilservicejobs.service.gov.uk^$stealth=dpi to AdGuard Base filter.
