Error 404 Not Found, not load visuals in service

Hi Anonymous ,

When publishing SSAS data sources to Power BI service, you need to configure the gateway first.

On the New connection screen for your on-premises data gateway, select Analysis Services for Connection type.

Fill in the information for the data source, which includes Server and Database. The gateway uses the information you enter for Username and Password to connect to the Analysis Services instance.

Configure the Privacy level for your data source. This setting controls how data can be combined for scheduled refresh. The privacy-level setting doesn't apply to live connections.

Optionally, you can configure user name mapping now. For instructions, see Manual user name remapping.

After you complete all the fields, select Create.

After creating it, go to the corresponding SSAS semantic model and select the corresponding gateway.
