@maxikuzmin can you reproduce this?

[jordanswrld94]

Also.happens with easylist

[jordanswrld94]

This issue does not occur on android 4.2 only 4.3 nightly

[jordanswrld94]

I tried old versions. Looks like everything worked fine up until 4.3 nightly 23

@jordanswrld94 checked also on the latest nightly version, but I didn't have this problem again. I tried with AdGuard Base filter, without this filter, and also tried with adding another filter, but the site is not blocked. In your case access to the site is restricted for a long time, or it only happens for a short period of time?

[jordanswrld94]

Hmm thats so weird.. it happens even with a fresh set of settings. Its a permanent block. As long as i have other filters enabled it is blocked

@jordanswrld94 please also send debug logs with reproduction times to devteam@adguard.com

I found it. Its blocking because of a cosmetic rule? Thats so weird

[jordanswrld94]

The weird thing is that nightly 22 it doesnt do that. I will just stick with nightly 22 until it can be fixed. But i do see the only thing that changed code wise between nightly 22 and 23 is dns libs. So it has to do with that im guessing?

@jordanswrld94 could you please clarify which filter you are adding to the DNS filters module? You can post a link to add this filter

@jordanswrld94 I'm not quite following you. Are you adding basic AdGuard filters to the DNS section?

[jordanswrld94]

Yes just adding the ones from the adblocking filters section.

[maxikuzmin]

@jordanswrld94 why are you adding these filters to DNS filters? Those filters are in the Filters section, and you can enable them there

[jordanswrld94]

Because i want to block them on dns level aswell

[maxikuzmin]

@jordanswrld94 but including filters in "Filters" is enough. There is a DNS filter in the DNS section, Easylist and Basic filter are included there. The filters you add to the DNS section are not intended for DNS filtering, it will have no effect. It's most likely this combination that is blocking access to sites.

Here is what will work for you. Don't forget to select RAW. You can read more about how DNS filters work here and here Read more about the syntax here

[jordanswrld94]

Ok. Thankyou.

@jordanswrld94 btw, maybe this is triggering the duplicate rules you opened another issue about. Please try leaving only DNS filters in the DNS section, and repeat that issue. Let me know the results in the issue about duplicate rules
