Fabric Pipeline Error - Connection

Thankyou, suparnababu8, for your response.

Hi danielkataoka,

We appreciate your inquiry through the Microsoft Fabric Community Forum.

Based on my understanding, the error message you are encountering typically occurs when the On-premises Data Gateway is unable to establish a secure connection to Fabric's service endpoint, brs.frontend.clouddatahub.net. This is usually due to network or firewall restrictions, or because the gateway version is outdated. Specifically, the gateway cannot reach the necessary Fabric endpoints over port 443 (HTTPS), possibly due to firewall or proxy settings blocking outbound access, or outdated gateway software.

Kindly follow the steps below, which may help resolve the issue:

1. Download and install the latest version of the On-premises Data Gateway.
2. From the gateway server, run the following command:
   Test-NetConnection -ComputerName brs.frontend.clouddatahub.net -Port 443
   If the connection is blocked, please coordinate with your network team to allow access to *.frontend.clouddatahub.net.
3. Check the proxy settings and, if a proxy is being used, configure it correctly for the gateway service account.
4. If the issue persists, uninstall the existing gateway, delete any leftover folders, and reinstall a fresh copy.
