High severitygateway
Power BI Refresh Error:
Failed to create a gateway. Try again
What does this error mean?
The Power BI service could not register a new on-premises data gateway. This appears in the gateway installer or the Power BI portal during gateway setup.
Common causes
- 1The machine running the gateway installer cannot reach the Power BI service endpoints
- 2A previous failed gateway installation left behind registry entries or service stubs
- 3The user account performing the installation lacks local administrator rights
- 4The gateway port (443 or 5671) is blocked by a firewall or proxy
- 5An existing gateway with the same name is already registered in the tenant
How to fix it
- 1Run the gateway installer as Administrator
- 2Check outbound connectivity to *.servicebus.windows.net on port 5671 and *.powerbi.com on 443
- 3Open Services.msc and ensure no stale 'On-premises data gateway' service entry exists — remove it and retry
- 4Delete any leftover gateway registration files in %localappdata%\Microsoft\On-premises data gateway
- 5Retry the installation from the Power BI portal (Settings → Manage gateways → Add) rather than the standalone installer
