semantic model refresh fail after credential update

Hi smeetsh 

This usually happens because the password change invalidates the stored credentials in the Power BI / Fabric service. Fixing it in Desktop only helps locally  the refresh in the service still uses the old credentials.

Go to your semantic model in the Power BI service >> Settings >> Data source credentials >> re-enter the updated login details for each data source (SQL, Warehouse, etc.). Once those are saved, the refresh should start working again.

If a gateway is involved, make sure credentials there are also updated. In most cases you don’t need to republish the PBIX  just updating the service credentials is enough.
