Data Flow debugging does not start in IR Virtual Network Mode.

Hi nichiek ,

Here are my thoughts about your problems. I think you can do these steps below:

1. Look at the logs for your self-hosted integration runtime (SHIR). You can find these in the Windows Event Viewer under the "Integration Runtime" section. This can provide more specific error messages.

2. Ensure that your SHIR can resolve and connect to the necessary endpoints. Use tools like nslookup and Test-NetConnection to verify name resolution and connectivity to your on-premises SQL Server and Azure Data Factory endpoints.

3. High memory or CPU usage on the SHIR machine can cause issues. Check the resource usage and ensure that the machine meets the recommended configurations.
