I follow this tutorial: https://support.google.com/a/answer/2644334
At the step 4, when I enter the Application ID of my App Engine app, and I click on Enable SSL for App Engine Applications, and I get an error "ERR_TOO_MANY_REDIRECTS" for "https://appengine.google.com/start".
I have tried with Chrome, Safari, and Chromium. With a cleared cache.
Do you have any suggestion which could help me?
Using a different superuser account in Google Apps worked to enable SSL. No clue why.
Once it was enabled by the other account, my original superuser account could be used to upload and manage the SSL Certs.
