Java JDBC Firebird错误连接被远程接口拒绝（GDS异常。335544421）

Question

public static void main(String[] args) {

    String databaseURL = "jdbc:firebirdsql://localhost:3050/e:/firebird/test.fdb";
    String user = "SYSDBA";
    String password = "masterkey";
    String driverName = "org.firebirdsql.jdbc.FBDriver";

    try {
        Class.forName(driverName);
        Connection connection = DriverManager.getConnection(databaseURL,user, password);

    } catch (SQLException | ClassNotFoundException e) {
        e.printStackTrace();
    }
}

有人可以帮助我解决此错误吗？

/ Library / Frameworks文件夹之外的数据库

在这种情况下，我使用Java 1.8 + Firebird 3.0 + Jaybird 2.2.12
