OIC Instance Login using Custom Domain URL

Summary:

Hi,

We have implemented below solution to secure OIC Instance URL.

Deployed below resources in OCI -

—> Load Balancer in Public Subnet, API Gateway in Private Subnet, OIC Instance

—> DNS record pointing to LB Public IP

Custom URL (let's say abcd.example.com) is working. In API Gateway, Deployment is done with wild card "/" and backend is OIC Instance Runtime URL.

I am trying to restrict the OIC instance Runtime URL from Network Access (by providing CIDR Range from API Gateway), OIC instance is getting restricted or blocked (it's expected) however with custom domain URL, i am getting login page but after providing the credentials it throws below error.
