This issue does still exist on 10.14.6. It seems to be "solved" by disabling DNS protection. I filed two support requests yesterday. On first occurring I got a dialog box warning that Adguard hadn't started properly. I had no connection and at first I simply re-entered Cloudflare DNS in System Prefs > Network > Advanced. After a reboot Adguard started up but I could connect to the Internet only disabling DNS protection.

The problem is still occurring with MacOS 12.2.1 and AdGuard Application version 2.7.0.1094 release (CL-1.8.276, DNS-1.6.72), where the problem occurs on one of three identically configuration systems. Notable is that when LittleSnitch is loaded the problem presents on boot. It appears there is a conflict with LittleSnitch. If AdGuard is set to not load on boot, but is started after the machine is stable AdGuard loads without issue. While I have tried to find why only one of the three systems has this issue, nothing in the logs points to an answer.

Additionally debugging is difficult given debug logging is always disabled on boot, even if enable prior to a reboot. Thus detailed logging, as required by AdGuard, has not been provided.

I should add resetting AdGuard's preferences to default doesn't help. Nor does cleaning out AdGuard and doing a clean install. Finally using the nightly yields the same results.

Perhaps it would be helpful if there was a way to force AdGuard debug logging at boot....

Hello @vsc42

OS version: 12.3 Beta / 11.6 BigSur
AdGuard for macOS: 2.7.0.1094 release (CL-1.8.276, DNS-1.6.72)
Little snitch version: Version 5.3.2 (6229)

The issue is not reproduced.
Please specify in what mode Little Snitch works.
Maybe there are some other features to consider?

In any case, you can send logs we tried to figure out the causes of the issue. (apple@adguard.com)
