Expected behavior

After giving consent to the OAuth2 Token, gcm manages the token refresh without further user interaction in the background. This means, once the token expired, gcm refreshes the token automatically. Git can successfully authentication without error.

Actual behavior

After giving consent to the OAuth2 Token, git throws an authentication error once the access_token expired. This triggers the deletion of the access_token. During the follow-up execution of git, the missing access_token triggers the refresh of the OAuth Token with gcm and updates access/refresh_token as expected. However, as a user, I always have one initial git auth error after token expiration.

What can be seen from the error-log is, that gcm validates the auth_token, does not recognize that it is expired, and proceeds without refresh. This results in a 401 auth error and the deletion of the access_token.
