Forbindelsen fik timeout:Nodejs Google App Engine til Cloud MySql

Det hjalp at bruge socketPath param under forbindelse til mysql.

var connection = mysql.createConnection({
        host     : 'ip_address',
        user     : 'root',
        password : 'password',
        database : 'database_name'
        socketPath: “/cloudsql/projectName:zone:instance-name”
    });
