@kingphoenix Think I found the cause, github master is updated will have a test zip up in the next couple days.

@Sventovit Update the add-on, the error messages are better defined. Then see below.

I've re-logged twice on 2 different installs with no issue.

With 5.4.6/5.5.0
if when signing in you get -- invalid_client : oauth client not found -- the client id is incorrect.
if when signing in you get -- invalid_client : unauthorized -- the client secret is incorrect.
if you try to access anything that requires api(ie. Popular right now) and get an error it's the api key.

Check on your keys in the developers console where you created them in case google de-activated them, and double check they are correct.
If it's still an issue, a full debug_log (wiki) may help.
