I'm using ADFS as an enterprise login solution for ArcGIS portal. Internally, it's working perfectly.

I set up a web application proxy server in the DMZ for authentication outside the local network. Login attempts there result in a 503 error. Looking at the event log on the WAP server, I see this:

The federation server proxy configuration could not be updated with the latest configuration on the federation service.

Additional Data
Error:
Retrieval of proxy configuration data from the Federation Server using trust certificate with thumbprint '<thumbnail>' failed with status code 'InternalServerError'.


I'm also getting eventID 394:

The federation server proxy could not renew its trust with the Federation Service.

Additional Data
Exception details:
An error occurred when attempting to establish a trust relationship with the federation service. Error: The underlying connection was closed: An unexpected error occurred on a send.

User Action
Ensure that the federation server proxy is trusted by the Federation Service. If the trust does not exist or has been revoked, establish a trust between the proxy and the Federation Service using the Federation Service Proxy Configuration Wizard by logging on to the proxy computer.


I've attempted to reestablish a trust relationship w/ the install-webapplicationproxy commandlet, but if fails, just telling me "the underlying connection was closed: an unexpected error occurred on a send."
