SFTP client cert auth

[codermapuche]

Hello, i want to make a sftp server with client cert auth, current i doing:

server = new ftpd.FtpServer(config.ip, {
        getInitialCwd:        function() { return '/';          },
        getRoot:              function() { return self.current; },
        pasvPortRangeStart:   config.pasv[0],
        pasvPortRangeEnd:     config.pasv[1],
        tlsOptions:           {          
                                key: fs.readFileSync(config.key), 
                                cert: fs.readFileSync(config.cert), 
                                ca: fs.readFileSync(config.ca), 
                                requestCert: true, 
                                rejectUnauthorized: true
                              },
        allowUnauthorizedTls: true,
        useWriteFile:         false,
        useReadFile:          false,
        uploadMaxSlurpSize:   7000
      });

With the same tlsOptions i success make an https server with client cert auth, so the keys are ok and valid, but when i try to connect with the sftp server, i have this log from filezilla client:

Estado: Conectando a 192.168.1.131:7003...
Respuesta: fzSftp started, protocol_version=8
Comando: keyfile "E:\virtual\certs\client1-key.pem"
Comando: open "cef@192.168.1.131" 7003
Error: Connection timed out after 20 seconds of inactivity
Error: No se pudo conectar al servidor

Debuugin i see that client send the command:

SSH-2.0-FileZilla_3.30.0

and here stop the connection, with winscp the command is

SSH-2.0-WinSCP_release_5.13.2

after some time of this command, the server show this error:

Client connection error: { Error: read ECONNRESET
at TCP.onStreamRead (internal/stream_base_commons.js:111:27) errno: 'ECONNRESET', code: 'ECONNRESET', syscall: 'read' }

i not have idea how to fix it, can help me please?
