NotAllowedError when trying to access AppStats

Question

After doing everything from here http://code.google.com/appengine/docs/python/tools/appstats.html I get

    <class 'google.appengine.api.users.NotAllowedError'>: 
Traceback (most recent call last):
  File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/appstats/ui.py", line 324, in <module>

    raise NotAllowedError

when trying to access myapp.appspot.com/_ah/stats or just myapp.appspot.com/stats/

Answer 1

Most likely you have created your app with authentication set to only allow users from your Google Apps domain, but you're attempting to access appstats via the appspot.com subdomain. Try again using the URL for your app on your custom domain.
