Problem upgrading data source in PowerBi web

Hi everybody,

We have a customer with NAV installed on a server. To connect to the server via rdp, I must use a VPN.

In my laptop, I've created a PowerBi report, adding 3 data sources from nav. Of course, VPN must be on,  and when adding the data sources I didn't have any problem, because I've added in the credentials one of the users we use to start session in NAV. Also, when I refresh data soruces, the changes in data are shown correctly.

But when I publish the report into the web version, and try to refresh data, I get a credential error. I'm trying to add into the credentials the same NAV account that i configure when adding the data sources into the desktop version, but I still get the error.

Why can be this happenning?


Thank you very much
