PowerBI Desktop report server client cannot connect to report server though application proxy

Hi Donald_Duck ,

Based on the details you've provided, it seems like you've successfully set up the application proxy for web connections, but are encountering issues with the PowerBI Desktop client.

Given the scenario, configuring Kerberos with SPN (Service Principal Name) and delegated control is indeed a critical step for supporting PowerBI Report Server desktop client connections through the application proxy.

Ensure that Kerberos Constrained Delegation (KCD) is properly configured for the application proxy connector.

Confirm that the application proxy connector is installed and configured correctly on a server that can communicate with the PowerBI Report Server.
