Postgres via PBI Service: No connection could be made because the target machine actively refused it

Hi ralwi65,

Thank you for reaching out to the Microsoft Fabric Forum Community.

Try these troubleshoot points:

Temporarily disable antivirus/firewall on the PostgreSQL host and test.

Try using IP address directly (if DNS might be masking something).

Create a local test report using the gateway machine with a simple connection string and try using that in the gateway.

Check for TLS/SSL enforcement mismatches between Gateway and PostgreSQL.

If the issue still persists, I’d recommend raising a support ticket with Microsoft. The support team can look into the backend and provide more in-depth assistance tailored to your environment.
