You gotta' add the port of the connection to the IP. Ex: 127.0.0.1:2883.

Don't use external MySQL hosts unless you want to experience poor performance and extreme delays in data transfers. Any respectable SA-MP host will offer you a database on one of their own servers.

You need to setup "Remote MySQL", but that is not available for free accounts on Hostinger. As others pointed out, external MySQL server is not recommended.
