I’m following an Authentication Quick Start (https://developer.okta.com/quickstart/#/okta-sign-in-page/php/generic) and when I run the code I am correctly redirect to the Okta login page. After successfully authenticating it attempts to redirect to my callback url and at that point the browser (multiple browsers) report that the site is not working due to excessive redirects. Below is the exact message from Chrome…
This page isn’t working
abc.xyz.com redirected you too many times.

I should mention that this is running in Google App Engine but I don’t know if that is causing this or not. Has anyone run into this issue before? Thanks is advanced.
