I am getting exception from google saying:
java.io.IOException: Received authentication challenge is null
I read that this is reproducing 401 error. So this
Indicates that the ClientLogin AUTH_TOKEN used to validate the sender is invalid.
But i have everything registreted and logined with ClientLogin successfully.
So what wrong could be?
