Scheduled Refresh with Essbase Connector

I have created a Power BI dashboard that uses a connection to Essbase.  I can manually refresh the data via Power BI Desktop, but I cannot schedule a refresh after publishing. The error message (below) says that my creditionals are invalid, but I used the same creditionals to import the data from Essbase.  Everything that I have built is useless if I cannot schedule a refresh.  Any help is appreciated.  

Error message:
