Answer:
It is possible that your Database Server is not set up to accept the remote connection using TCP Provider, the Database server is only listening to local traffic or traffic coming from a Private Network Adapter. Remember if you intend to allow remote access to the Database Server you have to take extra steps to secure the connection.
