Making a service call from apache between oidc

[Sugavanam]

Hello ,
I'm working on a developing a solution ,where I need to make a service call to a database to fetch userid and generate password and submit after the oidc authentication is done. Below is the flow

User ----> oidc authentication--> fetch user details ---> landing page of the application

I use lua script for the fetching and password generation ,submission processes

This works in centOS7 but not in redhat 8
I get "400 bad request this combination of host and port requires tls"

If you have any idea about this error .kindly guide me.
