Timed out while waiting for handshake

I have set redyTimeout to 99999, but it still connects time out. I use sftp on the command line, it works to connect my host. Please some suggestions on how can I process it. Thanks.

• nodejs version: v12.16.0
• ssh2-sftp-client version: 6.13.4
• OS: macOS Mojave 10.14.6

this is code

const SftpClient = require("ssh2-sftp-client");

const sftp = new SftpClient();
sftp.connect({
    host: config.sftpHost,
    port: config.sftpPort,
    username: config.sftpID,
    password: config.sftpPW,
    protocol: "sftp",
    readyTimeout: 99999,

    }
})
    .then(() => {
        console.log("connect SFTP!!");
        return sftp.list("/");
       // return sftp.get(remotePath, dst))
    })
    .then(() => {
        console.log("connect SFTP!!");
        sftp.end();
    })
    .catch(err => {
        console.error(err.message);
    });

this is debug log

About to push version v7.0.2, which is based on ssh2 1.3.0, that includes the patch to fix the timeout issue.

Sorry, I don’t use docker, so cannot help.

I do know that without exception, every report I have had which involves docker and connection issues has been due to a configuration issue with docker. It is usually related to the network stack and firewalls or MTU settings.

Are you able to connect from within the docker container using openSSH CLI? Have you done basic network diagnosis like pings, traceroutes DNS lookups, disabling firewalls etc?a Do the logs on the remote sftp server provide any clues (if you have access)? Have you tried connecting from the docker container to a different sftp server?

You probably need to seek assistance on a docker specific forum.
