Power BI Refresh Error:
UserErrorGatewayConnectionFailure

What does this error mean?

The SHIR failed to establish or maintain a connection to the data source or ADF relay service. All pipelines routed through this IR node are blocked.

Common causes

• 1The SHIR host machine is offline, restarting, or has insufficient resources
• 2Firewall or proxy rules on the SHIR host are blocking outbound connections to *.servicebus.windows.net (port 443)
• 3SHIR software version is outdated and incompatible with the current ADF service version
• 4The SHIR authentication key was regenerated in ADF but the node was not re-registered
• 5Network latency or packet loss between the SHIR host and Azure is causing connection timeouts

How to fix it

1. 1Check the SHIR host machine — ensure it is running and has adequate CPU/memory/disk.
2. 2Open Microsoft Integration Runtime Configuration Manager on the host and verify the node shows 'Online'.
3. 3Test outbound connectivity from the SHIR host: ensure port 443 is open to *.servicebus.windows.net and *.core.windows.net.
4. 4Check the SHIR version in Configuration Manager and update to the latest version if outdated.
5. 5If the auth key was rotated, re-register the node in Configuration Manager with the new key from ADF → Manage → Integration Runtimes.
6. 6Add multiple SHIR nodes for high-availability to prevent single-node failures from blocking all pipelines.
