The error means that the server address you used for the hostname is not working.
The server is not allowing the connection through that host name.
In the connection, the remote server address you used is:
wwww.lets-fishpettoys.com
Trying to visit that address does not work, it gives a server not found error. Since the server cant be found, it is probably trying to use the local host setting for connecting to the database
Double check the server name you are using.
