Hello, I'm glad to see you've found the solution.
This has happened because of ClientLogin Turndown on April 12th. The appcfg.py has been using OAuth 2.0 <https://cloud.google.com/appengine/docs/python/tools/uploadinganapp> as default authentication since May 2015 <https://code.google.com/p/googleappengine/wiki/SdkReleaseNotes#Version_1.9.20_-_May_5,_2015>. Additional information and instructions for migrating your application to be using OAuth 2.0 is available here <https://cloud.google.com/appengine/docs/deprecations/clientlogin#migrating_from_clientlogin_to_oauth_20> .
