Refresh DataSource from webpage XML?

I used Desktop to create a report using the Get Data > Web . It's an XML response and power bi was able to get all the tables.

When I published it to the web service, I got an error :

Your data gateway (Power BI – personal) is offline or could not be reached. Ensure the gateway computer is on and you are logged on to it during the scheduled refresh period.

But the API with XML response doesn't need auth. How do i get around this?
