Connecting remote mysql via local machine : node expressjs - mysql

Question

I am trying to connect to remote mysql(hosted on digitalocean server) and using the db for code in local machine.
When I start the node server and request for data, I get the following error.
{"ERRORMSG":"Something went wrong.{\"code\":\"ENOTFOUND\",\"errno\":\"ENOTFOUND\",\"syscall\":\"getaddrinfo\",\"hostname\":\"http://ip.of.remote.server/\",\"host\":\"http://ip.of.remote.server/\",\"port\":3306,\"fatal\":true}"}
After the first attempt, if I refresh again I get different error
{\"code\":\"PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR\",\"fatal\":false}
Connection is made like this:
connection = mysql.createConnection({
connectionLimit: 10000, //important
host: 'http://ip.of.remote.server/',
user: 'user',
password: 'password',
database: 'db',
multipleStatements: true,
connectionLimit : 100,
waitForConnections : true,
queueLimit :0,
debug : true,
wait_timeout : 28800,
connect_timeout :10
});
Call is made like this
app.get('/WSgetdata', function (req, res) {
var q = "CALL sp_get_data();"
var obj = {};
connection.connect();
connection.query(q, function (err, rows) {
if (err) {
obj.ERRORMSG = JSON.stringify(err);
}
else if((rows[rows.length-1])[0].ERRORSTATUS == 0){
//do something
}
res.end(JSON.stringify(obj))
});
});
What is wrong. It works fine when code and db are on same machine.
Also I have grant access to db from desired IP.
