Google Drive – Error: invalid_client

I am getting this message: “Click here to authenticate your Google Drive Account”. But when I click the link, I just get this:

Error: invalid_client

access_type=offline
state=token
display=page
prompt=consent

What do I need to change to have this function correctly?
I also have a multisite. Do I need to create a new Client ID for each website on the multisite?
