Blokada blocks all downloads of the stock LineageOS browser and all browsers available at F-Droid #209

Open Herbstfreud opened 6 years ago

Herbstfreud commented 6 years ago

Steps to reproduce

  1. Download a browser from F-Droid (for example Firefox Klar, JumpGo, DuckduckGo browser, Privacy Browser...) or use the stock browser from LineageOS 14.1
  2. Go to a websearch (for example Duckduckgo) and search for a picture ("test") while Blokada activated (Standard DNS, just standard blacklist).
  3. Try to download the picture to the phone.

Expected behaviour

The download icon in the status bar should appear, after the download the picture should be located in the download folder on the smartphone (or in the folder you have set in the browser manually).

Actual behaviour

The download icon appears for a blink of an eye and disappears again. The downloaded file cannot be found in the download folder. After several minutes the download icon appears again, together with the message that the download failed. With Blokada disabled same situation works, permissions have also been given to the browsers (if they have been asked for this, e.g. for storage). With some browsers (Chrome, Yuzu,...) from Play Store it works also with Blokada enabled.

Configuration

  1. Blokada version 3.3

  2. Device model Nexus 5 (also LG G4, Samsung Galaxy S2, Samsung Galaxy A5-2017)

  3. Android version / ROM All listed devices with latest LineageOS 14.1

Questions

  1. How long have you been using Blokada? Since beginning of 2018.

  2. How long time ago has the problem started to happen? Since the beginning.

  3. How often does this problem happen to you? Everytime.

Coudnt reproduce this!

Have you enabled Block connections without VPN option?

Have you tried whitelisting apps within Blokada?

Herbstfreud commented 6 years ago

What exactly do you mean with your first question?

Whitelisting the browser in Blokada or disabling Blokada are a theoretical solutin. I can use the mentioned browser (for example the stock LineageOS Browser) then. But whitelisting the browser in an Adblocker App is not really useful I think... ;) Other browsers like Chrome work without whitelisting.

I've forgot to mention that on the Samsung A5-2017 there is no LineageOS, just the stock Android 7, because I don't want to flash my company phone...

ghost commented 6 years ago

There is an option to make the vpn as always on vpn. Below that there is another option saying "Block connections without VPN", I don't know why but after enabling that option Blokada causes the same issue.

I am asking you to whitelist the download manager and not the browser, try whitelisting the download manager and then try again.

Herbstfreud commented 6 years ago

I have a German Blokada. Is it is possible that you mean the switch "Nur online", left of the hosts counter? It makes no difference for me in this case, whether the switch is on the left or right side.

Whitelisting the Download Manager has no Effect... also whitelisting of "Downloads" not.

ghost commented 6 years ago

No not that, I dunno how it is with Android 7. There should be a option in VPN Settings where it should ask if you want to set it as always on vpn...

Can you record this and upload the video? There is an app on fdroid called ScreenCam

I guess Chrome has its own download manager and is not using android download manager, have you tried with "Fennec F-Droid" ? If you can download with chrome then you should be able to download with Fennec. Try once with Fennec F-Droid.

Herbstfreud commented 6 years ago

That's cool with ScreenCam. :-) Where should I upload the video to? To the Telegram Channel?

By the way, with Fennec it works! That's interesting because I am sure I tried this also a few weeks ago and it didn't work...

ghost commented 6 years ago

I can confirm this now, I did a factory reset yesterday and with Blokada I am also not able to download from browsers like Firefox Klar, which use android download manager.

kar commented 6 years ago

Can anyone having this issue confirm that Firefox Klar and others actually work under ordinary VPN apps?

ghost commented 6 years ago

Yeahe everything works with a different VPN app, this is an issue with Blokada. Everything that uses android download manager is not working :(

Herbstfreud commented 6 years ago

@kar: Would it help to send you a logcat of this situation when I am trying to download something?

tarakbumba commented 6 years ago

Hi there. I'm also facing very same issue on my Mi Note 3 which runs on top of Android 7.1.1 based stock/Mine 9.1.4.0. I can't download anything using stock/Non-root Mi Browser and Android download manager. Note that com.android.providers.downloads is whitelisted.

ghost commented 6 years ago

I can confirm that. It's not working either under Android 8 and Firefox Klar. Can't download anything.

jesusoterogomez commented 6 years ago

I am experiencing the same issue. This is the same behavior as explained in https://github.com/blokadaorg/blokada/issues/79 , All Android download manager downloads are queued, and if you turn off Blokada before they time out, everything will start downloading.

It's inconvenient to whitelist all the apps where this is happening, because we still want to block the ads inside of these apps.

Right now, my dirty workaround is just disabling Blokada temporarily after I trigger downloads

Herbstfreud commented 6 years ago

So is there any chance to get this issue fixed in the future by the AOSP team?

Herbstfreud commented 5 years ago

Is there still the same behaviour on Pie?

androidacy-user commented 5 years ago

It doesn't block them on my phone, both Chrome and Firefox, the latter from F-Droid. This is Android 8.1 on Alcatel Tetra

racuna commented 5 years ago

Same here.

I'm on MIUI 10, Android 8.2

guy-teube commented 5 years ago

Same problem here (Blokada 3.7 installed from F-droid, on Lineage 15.1/Android 8.1.0) Whitelist doesn't work, I add apps, websites, hosts, but it's still blocked (download something from z browser, update content from a specific map,...)

ghost commented 5 years ago

Seems this was a issue with the download manager being outside the tunnel if whitelisted,try taking it off the whitelist(it's there by default) and try again. I've had this work before

Herbstfreud commented 5 years ago

This does not work for me... I still have the same behaviour that any download will be blocked.

soredake commented 5 years ago

Any progress on this?

kar commented 4 years ago

Reproducible on 4.3.5?

youri-- commented 4 years ago

Yes.

I've had this issue ever since I first installed blokada a couple of months ago. Still have this issue with latest version:

blokada/4.3.5 (android-28 full official arm64-v8a OnePlus-OnePlus6 touch api compatible) Android 9 (OxygenOS v9.0.9)

I've tried both with and without Android Download Manager & Downloads excluded in system apps. Other excluded system apps: com.android.carrierconfig Drive Duo Photos Gmail Google Play Store Phone/Message Storage Telephone Services (exact translation of these names may be off, because unfortunately I can't force blokada into English)

When for example blokada is active and I start Mixplorer and an update is available, I can see mixplorer.com was allowed (update check) in Host Log. Then I hit Download, but download doesn't happen. A few minutes later I get a < Download failed > notification. If I have blokada paused, it will start downloading immediately after tapping Download.

Herbstfreud commented 4 years ago

The issue is gone somehow... Maybe it was one of the Blokada updates, maybe it was one of the LineageOS/Android-Updates, I don't know. Just started to download something by DuckDuckGo Browser accidentelly and it downloaded with Blokada activated.

ghost commented 4 years ago

If you think it's fixed you can close this issue on your own discretion :)

Herbstfreud commented 4 years ago

But before that I'd like to know what happened exactly... Currently I don't know why it's working now and I think this should be clarified before closing this (for other people with the same issue).

In my opinion it is also possible that this has been fixed by a LineageOS update. Or maybe something else?

youri-- commented 4 years ago

I just noticed there is activity on this issue, please don't close this issue.

I still can't download anything using any browser when Blokada is active - currently v4.4.4 on Android 9, OxygenOS 9.0.9 stock, not rooted, OnePlus 6 (A6003). I get the download prompt and click download, or long-press an image and tap Save, then nothing happens and a while later (10, 15 minutes?) I get a notification "download failed" for an unknown filename.

If I disable Blokada new downloads start immediately and downloads I initiated while Blokada was active, that didn't work, suddenly start downloading, so I sometimes end up with more than 1 copy of the file I was trying to save.

PS. downloading through ADM (Android Download Manager) works fine regardless of Blokada.
