   import java.sql.DriverManager;
   import java.sql.ResultSet;
   import java.sql.Statement;
   
   // Press Shift twice to open the Search Everywhere dialog and type `show whitespaces`,
   // then press Enter. You can now see whitespace characters in your code.
   public class Main {
   
       public static void main(String[] args) throws Exception {
           Class.forName("org.apache.arrow.driver.jdbc.ArrowFlightJdbcDriver");
           Connection connection = DriverManager.getConnection("jdbc:arrow-flight-sql://192.168.0.220:33453/?useEncryption=false", "admin", "password");
           System.out.println("obtain connection ok");
           Statement statement = connection.createStatement();
           String str = "select 100;";
           ResultSet result = statement.executeQuery(str);
           System.out.println("execute query ok");
           while (result.next()) {
               int a = result.getInt(0);
               System.out.println(a);
           }

   I use go to test my code kind like this.
   ~~~
   package main
   
   import (
   	"database/sql"
   	"fmt"
   
   	_ "github.com/apache/arrow-adbc/go/adbc/sqldriver/flightsql"
   )
   
   func main() {
   	dsn := "uri=grpc://192.168.56.220:33453;username=admin;password=password"
   	db, err := sql.Open("flightsql", dsn)
   	if err != nil {
   		panic(err)
   	}
   	row := db.QueryRow("select 100")
   	var value int64
   	err = row.Scan(&value)
   	if err != nil {
   		panic(err)
   	}
   	fmt.Println("value:", value)
   }
   
   ~~~
   and I get this error.
   ~~~
    go run main.go
   panic: I/O: [FlightSQL] connection error: desc = "transport: Error while dialing: dial tcp 192.168.56.220:33453: i/o timeout" (Unavailable; AuthenticateBasicToken)
   
   goroutine 1 [running]:
   main.main()
           D:/gotest/main.go:20 +0x118
   exit status 2
   ~~~
   Is this means this is a server problem.
