The issue occurs due to networking interruptions between the Ingestion Utility and Flexera One. Outbound calls to the SaaS Management APIs, which provide the application list, are failing.

1. Verify whether there is an active service outage by checking Flexera Status.
2. If no outage is reported, verify that the system running the Data Ingestion Utility can access the SaaS Management API endpoints documented in Safelist URLs and Endpoints, specifically the entries for SaaS Manager.

NOTE: The Ingestion Utility uses the system proxy settings for networking control and cannot be configured separately.

Once the appropriate network configuration is applied, the Data Ingestion Utility will display the application list correctly.
