I am about to federate highly available hosting server with highly available portal (all components are fresh installation) I have set the properties of (Web Context URL, Private Portal URL) in portal administrator path before federating the hosting server to the Portal. As a test I wanted to access the portal through the private portal url to make sure that it is running but I could not do (page cannot be reached) I am able to reach the portal from the two machines without problems. I am not sure if this is the expected behavior given that the health check for external and internal load balancers are ok. Another note is that I accuse the certificate because it does not include the internal load balancer name.
The properties I have made are as follow.
"portalUrl": "https://Exloadbalancer.domain.com/portal"
"privatePortalUrl": "https://lbprivate.domain.com:7443/arcgis"
Any Advice will be appreciated.
The problem resolved. I was accessing the portal from a machine where port 7443 was closed.
