Hello,
I am getting during gateway setup for my Analysis Services data source.
"Unable to connect: We encountered an error while trying to connect to https://betaexcel.vivonet.com/excel/. Details: "Username needs to include a domain. Please use the format user@domain or domain\user and try again."Show details
Previously, I was able to create report in powerbi desktop then publish & schedule refresh, now power bi requires go thru gateway creation for online data source.
