Still struggling with PowerBI and Scheduled Data refresh using Excel and OneDrive via gateway

[Hikmer]

I've been trying to make this work for months, I was told there is a bug and it doesn't work.  Is this true? 

https://powerbi.microsoft.com/en-us/documentation/powerbi-refresh-excel-file-onedrive/

I am farily up to date with PowerBI and use it daily witht he Enterprise Gateway (newly installed) and I still get meaningless error messages that do nto help me figure out why this isn't working.  I expect the data in the model to refresh through the gateway....does it work?  If not wat is the secrect to making this function as advertised?
