pydrive: why has this vertification error suddenly appeared?

问题

I have a python script that downloads files from Google Drive using pydrive. This is the relevent bit of code:

def get_drive_object():
        gauth = GoogleAuth()
        gauth.LoadCredentialsFile("mycreds.txt")
        if gauth.credentials is None:
                # Authenticate if they're not there
                gauth.LocalWebserverAuth()
        elif gauth.access_token_expired:
                # Refresh them if expired
                gauth.Refresh()
        else:
                # Initialize the saved creds
                gauth.Authorize()
        # Save the current credentials to a file
        gauth.SaveCredentialsFile("mycreds.txt")
        # from http://stackoverflow.com/a/24542604/170243
        gauth.LocalWebserverAuth()
        return GoogleDrive(gauth)

Last week it suddenly stopped working, and gives an error of:

quitman$python update.py

I'm completely confused. I've tried generating a new mycreds.txt file, but I'm mystified as to how this error suddently appeared on code that had literally been running for years as a cron job...

EDIT: if I download the whole folder from server (dreamhost) to my local machine, the code runs fine... :s
