I have Node.js app, I'm trying to connect to an FTP server and list the folders/files that are in the FTP server folder.

The server is configured with: TLS/SSL Implicit Encryption

Here's my code:

async function listFilesInFtpFolder() {
  const client = new ftp.Client()
  client.ftp.verbose = true;
  try {
      await client.access({
          host: ftpConfig.host,
          user: ftpConfig.user,
          password: ftpConfig.password,
          port: ftpConfig.port,
          secure: false
      });

      // ********************** NOTE **********************
      // The execution never reaches here, it gets stuck in the 
      // ... previous statement until it times out
      // ********************** NOTE **********************

      console.log('connected');
      console.log(await client.list())

  }
  catch(err) {
      console.log(err)
  }
  client.close()
}

Getting this error:

Listening on port 3001
Connected to 155.66.22.88:6610

Error: Timeout (control socket)
    at Socket.<anonymous> (C:\Dev\my-app\node_modules\basic-ftp\dist\FtpContext.js:296:58)
    at Object.onceWrapper (events.js:298:28)
    at Socket.emit (events.js:209:13)
    at Socket._onTimeout (net.js:468:8)
    at listOnTimeout (internal/timers.js:531:17)
    at processTimers (internal/timers.js:475:7)

The execution never reaches these lines:

      console.log('connected');
      console.log(await client.list())

It gets stuck waiting for the access method until it times out For some weird reason the access method reports "Connected"

Note if I use a program like WinSCP (https://winscp.net/) to connect to this FTP server I'm able to connect and see the folders. But for some weird reason I cannot connect from nodejs. I tried many FTP libraries too.

assuming you are using ftp module from npm

according to the document https://www.npmjs.com/package/ftp#methods the secure option accepts mixed type, try 'implicit'

secure - mixed - Set to true for both control and data connection encryption, 'control' for control connection encryption only,

or 'implicit' for implicitly encrypted control connection (this mode is deprecated in modern times, but usually uses port 990) Default: false
