无法连接到MySQL数据库

I have a MySQL server on CentOS 7 and I want to try connecting a program written in Go to that database server. For the database server (MySQL) is work correctly and I tried to make one database and table.

MySQL username: golang
MySQL password: cobadatabase

CentOS 7 (MySQL Server) Machine's IP: 192.168.102.175:3306 (Default Port) and My laptop's IP: 192.168.102.170 **. So, Database server exist on different machine (remotely).

Here is my Go code:

func main() {
    /* Ini konekin database-nya dulu */
    app_database, err := sql.Open("mysql", "golang:cobadatabase@tcp(192.168.102.175:3360)/example")

    /* Nah klo ini Error Handling */
    if err != nil {
        log.Fatal(err)  // informasi log jika koneksi database gagal
    }
    defer app_database.Close() // Close koneksi jika benar-benar gagal
    /* End of Error Handling Connection */

    var (
        no string
        nama string
    )

    baris, err := app_database.Query("SELECT * FROM example_table")
    if err != nil {
        log.Fatal(err)
    }
    defer baris.Close()

    for baris.Next() {
        err := baris.Scan(&no, &nama)
        if err != nil {
            log.Fatal(err)
        }
        log.Println(no, nama)
    }
    err = baris.Err()

    if err != nil {
        log.Fatal(err)
    }
}

When I run my program, it fails with this error:

dial tcp 192.168.102.175:3360 connectex: A connection attempt failed because the connected party did not properly respond.
