Google OAUTH: The redirect URI in the request did not match a registered redirect URI

Question

I am trying to make an upload to YouTube from my Java based web app, I spent a few days to understand what and where is the problem and I cannot get it, for now I am pulling

Answer 1

I was able to get mine working using the following Client Credentials:

Authorized JavaScript origins

http://localhost

Authorized redirect URIs

http://localhost:8090/oauth2callback

Note: I used port 8090 instead of 8080, but that doesn't matter as long as your python script uses the same port as your client_secret.json file.
