unable to deploy in google app engine launcher: googlecloudsdk.core.credentials.store.RefreshError: invalid_grant

Question

I have been testing and deploying my application with no problem for 2 weeks. Yesterday, I got this error message after clicking the Deploy button. I have also tried to deploy by using command line (appcfg.py update applicationname), I got the same message. The application is running with no error from the GAE browser.

This is the last line of the log.

googlecloudsdk.core.credentials.store.RefreshError: invalid_grant

the complete message is here

If you type in your console gcloud auth login it will spawn manually the login process, click on the link to grant relevant permissions and after that you will be able to deploy.

You can also pass the parameter --no_cookies when you call deploy so you can force authentication every time.
