Does the Remote SQLServer grant access to your server your website is on?
You sometimes need to (Depending on security on servers) to grant access to a static IP address.
For example in a website I have created I need to access a database on site, and display information to users online. But to do this, on the server on site, I needed to allow firewall access to the website before it could connect properly

That site may help you set up firewall access.
