Issue Details

Steps to reproduce:

1. Enable AdGuard protection in the AdGuard app
2. Enable iCloud Private Relay in system settings
3. Open the Safari browser and visit the AdGuard test page

Expected Behavior

The AdGuard test page should confirm that the AdGuard Ad Blocker is active. Ads should be blocked on other pages in Safari.

Actual Behavior

The AdGuard test page indicates that the AdGuard Ad Blocker is not running. Ads are not blocked on other pages in Safari.

Screenshots

Screenshot 1

Additional Information

Ad blocking functions correctly in other browsers, such as Chrome.

Issue still exists as of 09/17 on the official public release of macOS Sequoia

@BrianHao Can you please specify, the problem happens only in first minutes after starting protection, or even after several minutes after?

[siddiqq]

same here , still not working on the official release, several minutes after starting

[sfionov]

@siddiqq
Can you please try to delete icloud.com from network.extension.exclude.domains advanced setting?

@sfionov facing the same issue here, it seems to improve blocking a bit, but still shows assets that should blocked (not sure how to quantify how much it helped though or if it's a placebo of sorts).

Attaching some screenshots here with and without private relay both having deleted icloud.com from network.extension.exclude.domains advanced setting.

Here's with PrivateRelay enabled

And with PrivateRelay disabled

Same experience here -

Same experience as the above - I am still seeing ads at all times, and have:

• deleted icloud.com from network.extension.exclude.domains advanced setting.
• Make sure I have the latest Adguard updates / filters
• Hard restarted Adguard, Safari, macOS

[legion-heresy]

As a workaround, changing AdGuard to run as an Automatic Proxy instead of a Network Extension resolved this for me. Go to AdGuard's settings > Network > General > Filtering Mode to change it.

Have the same issue
Pausing the Private Relay seems to help
Switching to Automatic Proxy mode blocks the ads but introduces network instability (timeouts while connecting and in the middle of transfer)

Thank you, is there a way to upvote the issue reported to apple ?

[sfionov]

In our tests filtering is working again on macOS 15.1 beta even with Firewall on.

I'm not sure if fix is present in 15.0.1 released today.

[baslia]

I just tried on 15.0.1 and the issue is still there, I guess we would need to deactivate icloud private relay until macOS 15.1 is released
