AdGuardHome blocked_hosts ignores AdBlock exception rules — any single disallow 'drops' all, making exceptions ineffective

I’m encountering an issue with the Disallowed Domains feature (blocked_hosts) in AdGuard Home. According

I’m encountering an issue with the Disallowed Domains feature (blocked_hosts) in AdGuard Home. It seems that when using AdBlock rules, any attempt to block domains results in all domains being dropped. For example, using

 ||*^ 

in blocked_hosts drops everything, and adding exceptions like:

@@||google.com^$important

doesn’t work. this would cause every single domain query to timeout and be dropped. .

Similarly if I:

||com^

all .com domains get dropped, and those queers time out as well.

Other Ad Block based rules also do not work, including regular express expressions and anything else I tried, whether using the UI or AdGuardHome.yaml

The only distinction it seems to make is between Prefix || which is a complete and utter drop of any expression following, which does not apply when using @@||, which is useless since without disallow/drop there is no relevance to overriding "allow.

This behavior is unexpected and not documented. I’m seeking a solution where only specified domains are allowed, while others are dropped without sending default blocked responses.

Steps to Reproduce:
1. Use ||*^ in blocked_hosts to block all domains.
2. Add @@||google.com^$important as an exception.
3. Observe that no domains are allowed.###

Expected result

Expected Behavior:

Exceptions should be respected, allowing specified domains to resolve.

Actual Behavior:

All domains are dropped, regardless of exceptions.

Thank you for looking into this.

“Since version 0.107.x, blocked_hosts supports AdBlock syntax for filtering rules. Errors might not reflect in the UI, but the feature is fully supported.”
