the only temporary fix is to disable strip parameters and dpi, and then the website loads

Fixed, update should be available in 2-3 hours.

@gcautonoma commented on Thu Feb 09 2023

hi thank you so much, but on pc fully fixed but on mobile still happens, and note that i am using duckduckgo but other browsers it happens aswell

@zloyden commented on Thu Feb 09 2023

The site opens fine on my end with our filters, DNS or stealth mode. What exactly causes it?

@gcautonoma commented on Thu Feb 09 2023

its the same connection closed when enabled strip parameters and dpi, also just to note that i have both dns filter enabled on adguard and android dns set the adguard dns server

@zloyden commented on Thu Feb 09 2023

Could you disable DNS, leave only protection from dpi in stealth options and AdGuard Base? Then update the filters in the app, clear cache in the browser, restart it and open the site. It was fixed by this rule and I can't reproduce it anymore

@@||elearning.ual.pt^$stealth

@BlazDT @AdamWr please also check this.

@gcautonoma commented on Thu Feb 09 2023

may be an incompatibility from the website it self, just saying

@gcautonoma commented on Thu Feb 09 2023

sorry for delay in response but after messing around that no matter what the only thing that causes it to not load is dpi with the rest on and that setting disabled it works

@zloyden commented on Fri Feb 10 2023

That's strange. Does the rule above helps in User rules? I mean this one https://github.com/AdguardTeam/AdguardFilters/issues/141783#issuecomment-1424252496.

@AdamWr commented on Fri Feb 10 2023

@AdamWr please also check this.

Website works fine on my Android device with Stealth mode and Protect from DPI option enabled. I can reproduce this issue only if I disable @@||elearning.ual.pt^$stealth rule.

Please ensure that filter lists are up to date.

@gcautonoma commented on Fri Feb 10 2023

ok, will check for updates

@gcautonoma commented on Fri Feb 10 2023

on my phone it keeps happening maybe other app or android setting is probably interfering, just leave it be

@AdamWr commented on Fri Feb 10 2023

If issue still occurs and it's caused by Stealth mode - Protect from DPI, then please try to add this rule:

@@||elearning.ual.pt^$stealth

to user rules and then check if website loads correctly.

@gcautonoma commented on Fri Feb 10 2023

i added that and still nothing

@AdamWr commented on Fri Feb 10 2023

Do I understand correctly that website loads fine if you disable Protect from DPI option in Stealth mode?

@gcautonoma commented on Fri Feb 10 2023

yes

@zloyden commented on Fri Feb 10 2023

Seems there is a problem with the app. I'll move it to another repo.

@gcautonoma commented on Fri Feb 10 2023

ok

maxikuzmin commented 1 year ago

@gcautonoma @zloyden I have this recurring, but the @@||elearning.ual.pt^$stealth rule helped solve the problem. Is this repeated in all browsers? I also noticed that at first the rule didn't work for me until I reopened the browser, try it

git2026 commented 1 year ago

yes it happens on all mobile browsers, its still not working, only with dpi off

maxikuzmin commented 1 year ago

@gcautonoma I should clarify, are you using AdGuard version 3.6.11?

maxikuzmin commented 1 year ago

@gcautonoma can you send me also your settings from app? You can attach them right here or send to email devteam@adguard.com

git2026 commented 1 year ago

can i send logs or should i send screen shots of the settings?

git2026 commented 1 year ago

AdGuard version 3.6.11, yes

maxikuzmin commented 1 year ago

@gcautonoma to troubleshoot this issue, we need to get additional logs.

Here's what we need you to do:

Collect the debug log as it's explained here;
Remember the exact time when the issue was reproduced. We will need it to find the corresponding records in the log file;
Additionally, capture the system bug report after reproducing the issue. Here's the instruction;
Send both files to devteam@adguard.com. Mention the Github issue number and the exact time when the issue was reproduced.

To unload the settings, you need to go to Settings -> General -> Export settings You can attach the settings to the debug logs

git2026 commented 1 year ago

sure i will do that

git2026 commented 1 year ago

done already sent the email

maxikuzmin commented 1 year ago

@gcautonoma thank you! We need some time

git2026 commented 1 year ago

no problem!

maxikuzmin commented 1 year ago

@gcautonoma please go to AdGuard settings -> Content Blocking -> Allowlist Uncheck elearning.ual.pt or just turn off Allowlist, that should help. We will fix this behavior in AdGuard version 4.0, which is already being actively tested and will be released in beta version soon, then in release version

git2026 commented 1 year ago

thank you it now works !!, as requested in the email could the logs and bug report that i sent be deleted since it contains sensitive information?

maxikuzmin commented 1 year ago

@gcautonoma yes, of course. Your logs and bug report have been deleted.

git2026 commented 1 year ago

thank you!
