Gateway Unreachable
Hi pdolan_tapco ,
Thank you for reaching out to the Microsoft Fabric Community Forum.
The FAILED result for ncu.frontend.clouddatahub.net means the gateway machine cannot reach a required Power BI Cloud Data Hub endpoint. When this endpoint is blocked, the gateway cannot open the Service Bus channel, which is why scheduled refresh is failing.
Please verify the following on the gateway server:
Allow outbound access to *.frontend.clouddatahub.net and *.servicebus.windows.net.
Ensure ports 443, 5671, 5672 are open with no SSL inspection or proxy filtering.
If you use a corporate firewall, Zscaler, or a VPN, bypass gateway traffic or whitelist all Power BI network endpoints.
After updating the network rules, re-run the Diagnostics. The gateway should report all checks as Success, and scheduled refresh will start functioning normally.
Thank you.
