Проблема сброса подключения при подключении к MS SQL Server (HA, Always On) из контейнера Java docker

Требуется помощь в решении указанной ниже проблемы.

Проблема : проблема сброса подключения при подключении к серверу Always On MS SQL из автономного приложения java, развернутого в java docker контейнер.

Примечание : автономное приложение работает нормально с windows, но не работает с docker образ, развернутый на linux.

Java код в отдельном приложении: 

public class SQLDatabaseConnection {    
    public static void main(String[] args) {
        String connectionUrl =
            "jdbc:sqlserver://SXXXXXXX05E:49001;"
                    + "database=AdventureWorks;"
                    + "user=yourusername@yourserver;"
                    + "password=yourpassword;"
                    + "loginTimeout=30;"
                    + "multisubnetfailover=true";
                    
        try (Connection connection = DriverManager.getConnection(connectionUrl);) {
             // Code here.
        }
        catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Версия драйвера :: ms sql -jdb c -8.2.2.jre8.jar

Docker Java базовый образ : openjdk 8. Java docker контейнер развернут на узле linux с использованием кубернетов.

SQL прослушиватель сервера (SXXXXXXX05E) (всегда включен) имеет два IP-адреса -> 10.100.200.111 - офлайн и 10.100.200.123 онлайн

Наблюдения : с MultisubnetfailOver = true и таймаутом 30 секунд, он пытается подключиться 3 раза.

Основная проблема, которую я вижу: когда два потока запускаются для установления соединения, сокет c onnector для результатов оффлайн IP-адреса, получаемых как УСПЕХ (см. -> Был выбран сокет следующего потока: SocketConnector: 9), после чего немедленно происходит сброс соединения. Я подумал, что автономный IP-адрес должен вызывать тайм-аут, и следует выбирать только разъем сокета с активным IP.

Пожалуйста, поправьте меня, если я ошибаюсь в своих предположениях, и помогите мне в решении проблемы.
