How should I resolve my appspot backup failure?

I'm trying to make a backup but it won't:

remote_api.py:

from google.appengine.ext.remote_api import handler

class ApiCallHandler(handler.ApiCallHandler):
    def CheckIsAdmin(self):
        login_cookie = self.request.cookies.get('dev_appserver_login', '')
        match = cookie_re.search(login_cookie)
        if (match and match.group(1) == MY_SECRET_KEY
            and 'X-appcfg-api-version' in self.request.headers):

    run_wsgi_app(application)


if __name__ == '__main__':
    main()

Update The server status is 302 and the method in remote_api.pyis not reached:

When using this approach to get remote API to work with open ID (from http://blog.notdot.net/2010/06/Using-remote-api-with-OpenID-authentication), I think you need to specify the secret key (ie 'thetopsecret') as the email when prompted (and then just hit enter when prompted for the password).

Use correct credentials. niklasro is not your email address.

If your app is using the High-replication datastore then your App-ID will be 's~montaoproject' (and probably needs to be in quotes on the command line? It certainly won't hurt to do so...).

[INFO ] Authentication Failed

It is nothing to do with GAE core , Authentication failed => either your login request failed or you are not providing the right credentials .

You are working behind proxy ? https is trouble behind squid proxy .

MY_SECRET_KEY corresponds with your login, not your password. You shouldn't need to actually enter a password (just hit return). So when you authenticate use:

Email: thetopsecret
Password for thetopsecret: (nothing)
