Databricks Error (SSL Certificate) With Refresh

Hi garynorcrossmmc
Thank you for being part of the Microsoft Fabric Community.

Please do check the below points that might resolve your issue. 

• Make sure SSL is enabled in the ODBC driver settings.

• Check that the certificate used by Databricks is from a trusted Certificate Authority (CA).

• If you're using a VPN or proxy, verify it isn’t intercepting or altering SSL traffic.

• Ensure the Databricks cluster you're connecting to is running and reachable.

• Use the latest version of Power BI Desktop—older builds can have SSL compatibility issues.

• In your microsoft.sparkodbc.ini file, enable detailed error logging:
  [Driver]
  AllowDetailedSSLErrorMessages=1
  EnableCurlDebugLogging=1
• Review the latest official guidance here: Power BI with Azure Databricks

If the above information is helpful, please give us Kudos and mark the response as Accepted as solution.
Best Regards,
