Description (last modified by kzar)


OS: Win10 Pro, Edition 1511, OS Build: 10586.122
Chrome: 48.0.2564.116
ABP: 1.11
Filterlists: Only the filter =adunit& with no filter subscriptions.

How to reproduce

  1. Login to my Google for Work Account (linked to jobp@…).
  2. Go to a YouTube video with ads (I use a VEVO channel):
  3. See the attached screenshot.

Observed behaviour

YouTube's error page is showing for the length of the ad.

Expected behaviour

The video should play without a video ad or error message.

Other information

Interestingly, I am only able to reproduce this issue from my Google for Work account. I can not reproduce with my personal Google account. Therefore, it could be somehow related to this?

Two requests are blocked by the filter:,0.007:B,0.067:ER&cmt=0.007:0.000,0.067:0.000,0.067:0&;rc.0&bh=0.067:0.000&bat=0.067:1:1&vis=0.067:0

Only the first request seems to be related, if you whitelist it the advert will be displayed and the error goes away. (See this paste.) If you whitelist the second request the error is still shown.

According to some of the discussions there is a work around, switching off "Ads based on your interests" (online and offline) on the Google Ads Settings page.

For me those settings were already switched off, but I can't reproduce the issue even after switching them back on.

The next thing we want to do is to verify the issue still occurs with only the filter =adunit& enabled (and no subscriptions). That would simplify the reproduction steps.

Also a screenshot of any (expanded) exceptions and warnings thrown in the console could be useful to further diagnose what's happening.

It's still happening with only that filter in ABP. There is another blocked request:,0.007:B,0.067:ER&cmt=0.007:0.000,0.067:0.000,0.067:0&;rc.0&bh=0.067:0.000&bat=0.067:1:1&vis=0.067:0 but it's also not working if you whitelist that one.

Feels like the issue was fixed, I assume on Youtube side, me and Job were not able to reproduce it again with our accounts that were having that issue.
