We have an externally exposed Enterprise deployment (10.8.1). Each individual component works over the internet BEFORE we federate Portal and Server. Once we federate Portal and Server, we are getting errors when trying to access our Server Manager via the internet.
I believe, but am not certain, the issue is that the Portal URL in Server Manager is using the internal URL for the Portal (ex: https://servername/webadaptor) and not the external URL (ex: https://gis.webdomain.gov/webadaptor).
Is there a specific workflow when exposing your Enterprise externally to the internet? Or, is there a reason why once we federate our Portal and Server, the internet side of things are not working as expected when they do work internally?
