Greetings, 

I have tried to create a folder source in Power BI Service but it could not be possible. This is the error. Could you help me please?
It works in Power BI Desktop but when I try to create it in PBI Services its impossible.

Hi. When using the gateway to connect to a local file you should use the DOMAIN on the authentication. Be sure you are using the structure "DOMAIN\Username" for the user name at windows username. If you are not sure what's the domain, just look for "This PC" and use the Device Name as domain.

I hope that helps,
