Suddenly getting 403 (Forbidden) with Oauth 2.0 consent on YouTube V3 API

I have 3 youtube brand accounts with channels. To two of them I'm connected and successfully authenticated, but the third one gives me a 403 error when I try to authenticate.

I use the python youtube upload script. I have set up the credentials and projects, enabled YouTube v3 api and everything. I did it couple of hours ago for the 2nd account and now the 3rd one is not working.

What could be the issue?

  1. Choose your account or a brand account to continue to youtubeupload:
    • I choose a brand account I manage (but I do not own it, only manage).
  2. Error 403. That’s an error. We're sorry, but you do not have access to this page
Solution

  • The issue should be resolved now. As part of rolling out the new signin experience a bug was introduced that caused the issue. We have rolled back to the previous behavior while we fix the root cause.
