Method 1 – Disabling Firewall/Anti-Virus Software on Your Computer

One of the possible reasons for this error is that the firewall and anti-virus software on your computer is preventing FileZilla from making a connection.

If that’s the cause of the Error: Connect econnrefused – connection refused by server error, simply disable the firewall and anti-virus software on your computer and try to reconnect. Here’s how to do so on Windows:

  1. Press the Windows key on your keyboard and type in Control Panel.
  2. Head to System and Security and locate Windows Defender Firewall.This image shows you system and security in Windows. This image shows you the System and Security on Windows.
  3. On the left menu bar, find the option to Turn Windows Defender Firewall on or off.Esta imagen muestra la configuración del cortafuegos de Windows Defender en Windows para corregir el error ECONNREFUSED: conexión rechazada por el servidor.

  4. On the next window, modify the settings to turn off Windows Defender Firewall for public and private networks, then press Ok.

On macOS, you need to:

Method 2- Changing FileZilla’s Default Port Value

Sometimes, the error happens because you’re using the wrong port when connecting with FileZilla. If that’s the case, all you need to do is put 22 (default SFTP port) instead of 21 (default FTP port number) on the port column, as seen below.

Important! Make sure to edit the Site Manager’s configuration and change the protocol to SFTP – SSH File Transfer Protocol if you’re using port 22.

Method 3 – Editing FileZilla’s Network Configuration Wizard

Si ninguna de las soluciones anteriores funciona, intente editar las configuraciones de red de FileZilla para corregir el ECONNREFUSED: conexión rechazada por error del servidor. Para acceder al Administrador de configuración de red , esto es lo que debe hacer:

  1.  Conéctese al cliente FTP de FileZilla y diríjase a Editar ->  Asistente de configuración de red .This image shows you how to find the Network Setup Wizard in FileZilla This image shows you how to find the Network Setup Wizard in FileZilla
  2. Tap Next to continue once a Firewall and Router Setup Wizard window appears.
  3. Choose Passive (recommended) as the default transfer mode and check the Allow fallback to another transfer mode on failure option .This image shows you how to change the firewall and setup wizard in FileZilla This image shows you how to change the firewall and setup wizard in FileZilla
  4. Select Use the server’s external IP address instead .
  5. Choose Get external IP address from the following URL . If the input field is empty, enter the default value, which is http://ip.filezilla-project.org/ip.php , and continue.
  6. Leave the port range settings unchanged and select Request a port from the operating system .

Now all you have to do is make sure everything is set up correctly. Click the Test button and FileZilla will try to connect to probe.filezilla-project.org to perform some simple tests.

If you don’t get any errors while testing, try logging into your hosting account again and you should log in with no problems. If you still see the message ECONREFUSED: Connection refused by a server error, please contact your hosting’s customer support team for assistance.
