Error with automatic refreshes for Databricks source: Authentication/authorization error occurred

Hi Sunflower7500,

Thank you for reaching out to Microsoft Fabric Community.

Thank you Deku  for the prompt response.

It’s likely related to how Fabric Capacity handles authentication differently than Pro. PATs sometimes don’t play well in Fabric refreshes due to security model differences. Try switching the Databricks connection to use OAuth2 in Power BI Service instead of a PAT. Also check your dataset’s credentials and gateway settings in the Fabric workspace.

If those don’t help, then go for opening a support ticket as suggested by Deku.

I recommend submitting your detailed ticket below:
