Simplesamlphp redirect after IdP authentication to HTTP instead of HTTPS

[zubermohammad]

Hi,

I have configured simplesamlphp on drupal 8 with the Apigee Kickstart project on an NGINX server. The integration was working on HTTP with my IdP which is Oracle Access Manager and dev portal was able to create users for federated authentication.

But when I applied SSL certificates on the LB behind with SSL Offloading, I am able to authenticate with IdP but the redirection from IdP is coming to HTTPS and being sent to HTTP from SimplesamlPHP.

I researched on this and found an article having the same issue.https://groups.google.com/g/simplesamlphp/c/PxMANEWt7Fk

Can someone please help how can I get this resolved?

Thanks...
