ERROR_DESTINATION_INVALID when publishing my website in Windows AZURE

Question

I created the ASP.NEt WEB API. I want to host this on Windows AZURE. I successfully created a website in Windows Azure and uploaded the publishing settings files for it. Now, when I publish my web API with VS-2012 on a machine running Windows 8, it asks me to import the publish settings file that I recently downloaded. I provided him with this file, and when I click the "Test Connection" button, it does not work. It gives the following errors.

I want to mention that I am behind a corporate firewall and use a proxy connection. If this is due to a firewall or proxy, then tell me that I can change my firewall / proxy settings to make it work.

Thanks at Advance ...
