隧道上的HTTPS

ssh -L 8000:dev.mycompany.com:443 jump.mycompany.com

现在我想用Jsch来模拟:

    public static void openTunnel() {
    JSch jsch = new JSch();
    String privateKey = "~/.ssh/id_rsa";
    try {
        jsch.addIdentity(privateKey);
        log.info("Connecting to {}@{}", getJumpUser(), getJumpServer());
        Session session = jsch.getSession(getJumpUser(), getJumpServer(), 22);
        session.connect();
        session.setPortForwardingL(8000, getHost(), 433);
    } catch (JSchException e) {
        log.error("", e);
    }
}

但是,在隧道设置之后,我遇到了以下异常,并尝试使用restemplate连接到它(Spring HTTP Client-但是curl也给出了一个错误):

ssl.SSLHandshakeException: Remote host closed connection during handshake
