Error during file transfer

[bachawiss]

Hello

I setup an FTP server in my js script using ftp-srv, I noticed that there's an errors on the transfert (it was working before)
If I use my FTP client, with a public FTP server, it works well.

Here's my code:
const port = 21;
const ftpServer = new FtpSrv({
url: "ftp://127.0.0.1:" + port,
pasv_url:'ftp://127.0.0.1' ,
anonymous: false,
});
ftpServer.on('login', (auth, resolve, reject) => {
if(auth.username === 'user' && auth.password === 'password'){
const rootFolder = ((__dirname)+"/../../data/test_cases/");
log.info('Authentication successful, FTP running under:'+rootFolder);
return resolve({ root:rootFolder });

        }
    });
    ftpServer.listen().then(() => {
        console.log('Ftp server is starting...')

    });

The error message:
{"name":"ftp-srv","hostname":"2fda095d0724","pid":125592,"id":"a0fe1dfd-2d6f-4bb2-8c60-850158af3799","ip":"127.0.0.1","level":50,"err":{"message":"read ECONNRESET","name":"Error","stack":"Error: read ECONNRESET\n
