    What is the data source?

     

    If it's SharePoint Online check the main PBI support site:

     

    https://powerbi.microsoft.com/en-us/support/

     

    Power BI customers with Premium Capacities using SharePoint Online as a data source may see refresh not complete successfully with the following message - "The underlying connection was closed: An unexpected error occurred on a send". Power BI and SharePoint Engineers are investigating the issue and an update will be provided soon.
