Error with OAuth2 Services authentication

I have successfully used the following code for an application that I have been using for 2 years but, in the last few weeks I have encountered the error "There was a problem communicating with Google servers" The code has not changed because I suspect that Google has made some change in the authorization form of the tokens. This error occurs on devices with Android 4.1, but the same code continues to work correctly with version 4.4. I have already tried to clear the cache of the app, and change the hosts file but it did not work

This is the code used:

am.getAuthToken(me, "oauth2:https://mail.google.com/", null, getActivity(), new MainActivity.OnTokenAcquired(), null);

The logcat shows the following message
