Issue with Azure Analysis Services connection in Power BI service

I'm having trouble getting a dataset deployed to the Power BI service work with Azure Analysis Services. My scenario is:

• I have create an Azure Analysis services server in my MSDN Azure Tenant
• I have granted access to this tenant with my work account
• Using my work account, I have deployed a Tabular model to Azure Analysis Services
• I have connected Power BI desktop to Azure Analysis Services and successfully connected to the database
• From here I can build an example report in Power BI desktop
• I then publish the Power BI desktop file to our Power BI tenant (I have tried both publishing to a normal workspace and an embedded capacity)
• When I open the report or the dataset in the Power BI tenant I get the error "
   
  Cannot Load the Model: Couldn't load the model schema associated with this report. Make sure you have a connection to the server, and try again. Please try again later or contact support. If you contact support, please provide these details."
• To debug this I tried editing the credentials. It appears to connect successfully but the error persists

Is there something I have done incorrectly? What else could I try to debug this?
