The ArcGIS Enterprise portal is unable to retrieve full configuration details from the hosting server

Description

When monitoring the organization logs in the ArcGIS Enterprise portal to retrieve full configuration details from the hosting server, the following warning message is returned:

Warning:
Using defaults for some properties of the self resource (ex: supportsSceneServices). The hosting server may not be reachable.

Cause

The following are possible causes for the warning message:

• Windows Authentication is enabled. Windows Authentication allows the system to use Windows credentials for authentication instead of prompting for login. If credentials are required but not passed correctly, users may encounter login prompts or access denials.
• The federation validation is incomplete. Although the federation setup may be marked as complete, the ArcGIS Enterprise portal may not have successfully retrieved all necessary settings. For example, when installing and configuring ArcGIS Web Adaptor, the process may sometimes stop midway. However, the configuration may still appear as completed despite the incomplete validation.
• The hosting server has stopped. The ArcGIS Server instance designated as the hosting server is no longer running or responding. This prevents the portal from managing and serving hosted services, leading to disruptions in web maps, applications, and data storage.

Solution or Workaround

Depending on the cause, use one of the workarounds below to resolve the issue:

Disable Integrated Windows Authentication (IWA) for ArcGIS Server

Disabling Integrated Windows Authentication (IWA) and setting ArcGIS Server to anonymous access allows the ArcGIS Enterprise portal to communicate with the hosting server without authentication barriers. This prevents validation issues and ensures necessary service properties, avoiding warnings about unreachable servers.

1. Open Internet Information Server (IIS) Manager.
2. In the Connections panel, locate and expand the website hosting the ArcGIS Web Adaptor.
3. Click the name of the ArcGIS Web Adaptor.
4. In the Home panel, double-click Authentication.
5. Select Windows Authentication and click Disable.
6. Select Anonymous Authentication and click Enable.

Manually validate the hosting server in the ArcGIS Enterprise portal

By manually validating, the portal establishes a confirmed connection with the hosting server, ensuring that all required properties are correctly retrieved. Refer to Portal for ArcGIS: Manage a server site for instructions.

Restart the ArcGIS Server service on the hosting server machine

Restarting the ArcGIS Server service restores communication with the portal, clears system errors, and ensures essential processes are running properly. Refer to How To: Start and stop ArcGIS Server machines using the ArcGIS Server Administrator Directory for instructions.
