Dax Studio is constantly disconnecting

Hi danielpitz  ,

Thank you for reaching out to Microsoft Fabric Community Forum.

Microsoft updates and releases Power BI Desktop monthly, and only the latest version of Power BI Desktop is supported. If you experience issues with Power BI Desktop, please ensure you are using the latest available version.

Power BI semantic model behavior depends on the storage mode. Import mode semantic models require data refresh to update imported data. DirectQuery semantic models do not import data; instead, they query the underlying data source when users interact with reports or visuals.

For DirectQuery models, the performance and response time depend on the underlying data source because queries are sent to that source during report interactions.

Regarding external tools, Power BI Desktop supports external tools that are installed locally and registered with Power BI Desktop. When launched from the External Tools ribbon, Power BI Desktop passes connection information to allow the tool to connect to the model. External tools are provided by third-party contributors, and Microsoft does not provide support or documentation for those tools except for the underlying public Microsoft APIs.
