This of course is not really a solution at all. The only thing that works is to have the users with the problem access my app on the appspot address: The problem occurs on various browsers and operating systems, so I don't think it pertains to a particular setup. On some other SO posts about redirect loops people suggest that some of these auth pages are getting cached, but I've checked and all of them use a 302 redirect which doesn't get cached.Īlso, I've had the users with the issue clear their browser cache and cookies and make sure they are NOT blocking third-party cookies, but none of this helps. However, one of my users reported that it seemed to be looping between these two addresses: I am unable to reproduce the redirect loop with any of my test accounts or machines.

The main page has login required: get(self): It's worked fine for the last 3 years, and the only thing that has changed is that it now goes to https instead of http: loginURL = users.create_login_url('') This is the code I'm using to create the login url. (ERR_TOO_MANY_REDIRECTS) like the image below when they attempt to login. HOWEVER, a handful of Google Account users get a redirect loop error Most users who login with their Google Accounts don't have any problems either. There are no problems at all for users who login with their Google Apps accounts (which uses OpenId). I have setup SSL (VIP) for a custom domain on my Google App Engine app ( ).Įverything works fine for most of my users.
