Azure hosted website - FormsAuthentication not routing to defaultUrl

Question

I have the following setup in my Web.Config:

<authentication mode="Forms">
    <forms loginUrl="Landing/Login.aspx" defaultUrl="~/Member/Dashboard.aspx">
      <credentials passwordFormat="SHA1"></credentials>
    </forms>
</authentication>
<authorization>
    <deny users="?" />
</authorization>

This correctly redirects when testing on locahost, but when published to Azure, logging in just redirects to http://mysite.azurewebsites.net/ and not http://mysite.azurewebsites.net/Member/Dashboard.aspx as described in the Web.Config. Interestingly enough, however, trying to navigate to a page without logging in correctly redirects to the defined loginUrl="Landing/Login.aspx". Should I be using the FQDN in this case for the defaultUrl? Are forms authentication not setup on IIS of my Azure server? Please advise.
