DM_GWPipeline_UnknownError
Power BI dataset refresh error — what it means and how to fix it.
What this means
A generic gateway-pipeline failure — the gateway could not reach the source (for a SAML source, the signing key was not loaded).
How to fix it
- Verify the data source is reachable from the gateway host.
- Check the gateway event logs for the underlying error.
- For a SAML source, reconfigure the signing certificate.
