@bestpika if you disable user filter for a while, would the issue be still reproduced?

[bestpika]

@northis My user filter is empty.

And the request seems like timeout

[bestpika]

I also try to disable Ad Blocker, the issue still reproduced.

[bestpika]

The only way to solve this issue is add the domain to HTTPS filtering exclusions.

[northis]

And it was ok before 7.3 nightly 2, wasn't it?

[bestpika]

@northis I found this issue since 7.2.2946 NIGHTLY (CL 1.5.75).

[northis]

@bestpika ok, send us logs to devteam@adguard.com, please. With debug level would be better.

[bestpika]

@northis I've sent it.

[northis]

@bestpika Thank you, we got it. But perhaps it is not enough. Could you please restart AG with /trace flag like that "C:\Program Files (x86)\Adguard\Adguard.exe" /trace (for ex., set target in shortcut), reproduce the issue and than send us logs once again? You can remove this flag after.

[bestpika]

@northis I've sent it.

I found another site has the same issue.

@bestpika got your logs, thanks. Logs are ncloud.

[ameshkov]

@bestpika do you use any proxy/vpn extension/app?

[bestpika]

@ameshkov No. I only use AGH and AG for Windows. And on my Windows 10 pc, the antivirus is Microsoft defender. And I can 100% reproduced this issue on my two different pc (different operation systems).

[ameshkov]

Is this issue specific to CentBrowser? Have you tried Chrome?

[AdamWr]

I have similar issue in Chrome.

[bestpika]

@ameshkov Chrome has the same issue.

[ameshkov]

Guys, please re-test it with today's nightly version. There's a bug fixed there that seems to be relevant to this issue.

Expect it to be out in the evening.

[AdamWr]

It seems that it works fine with latest nightly build (version 7.3 nightly 8 (build 2976, CL 1.5.122)) :)

[ameshkov]

Thank god!

@bestpika does it work okay in your case?

[bestpika]

@ameshkov Oh, let me try it.

I think the issue is solved. Good!

[ameshkov]

Awesome, thank you!
