![]() ![]() ![]() See my article about Network configuration for FTP passive mode for details. If that's the case, most usual problem is that some firewall (or the NAT) on the way between you and the server blocks the connection attempt to the data port (as reported in the response to the PASV command). Though as you mention that "Browsing is nearly impossible", it looks like that it does not help. Status: Connection established, waiting for welcome message. Error: Failed to retrieve directory listing Status: Connecting to 117.247.9.3:2555. ![]() So in most cases, you won't notice the problem at all. Error: The data connection could not be established: ECONNREFUSED - Connection refused by server Response: 425 Cant open data connection. Set Transfer Mode set to Active, it works. Tested with Plain FTP - same result (ECONNREFUSED) with Transfer Mode set to Default. Note that FileZilla will always use MLSD if the server supports it, Active mode doesnt change that. When encountering this, FileZilla tries to connect to the primary address of the FTP server instead, as that is usually the correct address to use. By using Active mode, you merely worked around this presumed server issue. You should see the offending address in the FileZilla log: FileZilla does too and reports the mentioned message. The FTP server must report its external IP address, that can be used outside the NATted networks.Īs this is unfortunately a common issue, many FTP clients try to detect this (by checking that the reported IP address is within the range of addresses reserved for local communications within a private network). It's clearly a misconfiguration of the FTP server. When it reports such IP address to a client outside the NAT, the IP address is obviously of little use. FileZilla Status: Connection attempt failed with 'ECONNABORTED - Connection aborted', Error: Could not connect to server & Error: Failed to extract certifica. And it's aware of its local address within its NATted network only. It's quite common though that the FTP server is behind a NAT. Método 2 para reparar el error ECONNREFUSED: Deshabilitar cortafuegos, antivirus, o un programa similar que pueda estar bloqueando la conexión. The client should connect to that IP/port to initiate the transfer. Command: MLSD Error: The data connection could not be established: ECONNREFUSED - Connection refused by server Error: Connection timed out Error: Failed to retrieve directory listing As far as I understood, it's the server configuration fault. The server responds with its IP address and port number. To establish a data connection for a file transfer or a directory listing, an FTP client (in the passive FTP mode) sends PASV command to the server. ![]()
