Connect Tableau to Power BI dataset

Hi 

I am trying to connect Tableau desktop(2018.2 version) to Power BI datasets. But i am getting an error saying:

I am a premiuim user and am a memer of the workspace where we have published the dataset. I am using the connection string to connect to the dataset from tableau.

Here is the error I am getting:

Unable to connect to the srever. Check that the server is running and that you have access privileges to the requested database.

Thanks
