Power BI Refresh Error:
DM_GWPipeline_Gateway_NetworkUnreachable
What does this error mean?
The gateway machine cannot reach the target data source over the network. The host is either down, has moved, or is blocked by a network rule.
Common causes
- 1The data source server was migrated to a new IP address or hostname without updating the connection string
- 2A network security group (NSG) or firewall rule was updated to block the gateway's IP
- 3The data source server is down or its database service is not running
- 4DNS resolution on the gateway machine is returning the wrong IP for the source hostname
- 5A VPN or ExpressRoute connection between the gateway and the source network is down
How to fix it
- 1From the gateway machine, try to ping or telnet to the data source server and port
- 2Verify DNS resolution: run 'nslookup <hostname>' on the gateway machine to confirm it resolves to the correct IP
- 3Check whether the source server is online by connecting to it from another machine on the same network segment
- 4Review any recent firewall or NSG changes that might affect traffic from the gateway machine's IP
- 5If the source was migrated, update the connection string in Power BI Desktop and republish, then update the gateway data source
