title: Error when trying to configure Power BI Data Gatwewy
body: <p>Just installed Power BI Data Gateway on one of the companies servers.</p>
  <p>The processes was smooth and very easy, I have assigned a name to the Data Gateway.</p>
  <p>As it is linked to my email (I think this is going to be another problem when other employees trying to publish their reports), when I tried to configure datasource in my Gateway I get this error !</p>
