Migrating ASP.NET Membership Database to SQL Azure

I am trying to migrate a database from SQL Server 2008 to SQL Azure. The database that I am attempting to migrate includes the ASP.NET Membership database (http://www.asp.net/web-forms/tutorials/moving-to-aspnet-20/membership). This database works fine when I run it in my SQL Server 2008 database. However, when I try to authenticate a user against SQL Azure, I receive an error that says:

Bad Request – Invalid Hostname with Asp.net WebAPI project in Visual Studio 2013

I am running a very basic webAPI project in Visual Studio Pro 2013. It runs fine on localhost on my machine. I then try and go to a browser from a different machine and goto :57571 similiar to how i could point to rails apps by putting the servers ipaddress followed by the port number. I then get
Bad Request – Invalid Hostname HTTP Error 400. The request hostname is invalid.
