Automatic Refresh setup error using Dynamics NAV (cloud)

Trying to setup automatic refresh.  Data source is Dynamics NAV (OData) and I am using the same credentials for NAV and Power BI.  I keep getting the following error - looking for some help out there :)  Thanks

Your data source can't be refreshed because the credentials are invalid.  Please update your credentials and try again.

OData - Edit credentials

Thanks in advance for your help
