  • The site manager creates and stores a list of FTP servers and their associated data.
  • Allows you to drag and drop methods, files, and folders, as well as make changes to them.

How to Connect to a Server and Transfer Files Using FileZilla, follow these steps:

  • From the menu bar, choose Filezilla, which has been installed.

After you’ve completed your successful installation, you might run into some technical difficulties connecting to FTP or SFTP. In most cases, these problems are caused by incorrect login credentials or incorrect remote connection methods. Let’s take a look at some other factors that can lead to a critical error: could not connect to a server in FileZilla.

Causes for Could Not Connect to Server in FileZilla:

Incorrect FTP Port Number

A secure FileZilla port number is usually considered to be 22. As a result, if you want to use the secure file transfer protocol (SFTP), change the default port number to 22. The error message, could not connect to server in FileZilla, can be caused by an incorrect port number.

Connection Issues & Active Mode

FileZilla uses Active mode connections by default to transfer files. FTP connections in Active Mode are not firewall-friendly, which may cause connection issues.

Incorrect Login Credentials

Several users, as is customary, receive the error Could not connect to server in Filezilla due to incorrect login details. We recommend that our customers double-check their user ID and password to ensure they are entering the correct credentials.

There Are Too Many Connections

You’ll get the critical error: could not connect to the server in FileZilla if your FTP server receives too many connections at once.

Solution – Critical Error: Could Not Connect to the Server in Filezilla 

Examine the Network Configuration

Verify if you have a successful local network configuration before moving on to the troubleshooting steps for the above-mentioned causes.

If there are any problems with the network or router settings, you’ll get an error message like this:

“Status: Connection attempt failed with “ECONNREFUSED – Connection refused by server “

To fix the issue, follow the steps below

  • Go to the Main Menu and select the Edit option.
  • Select Network Configuration Wizard and select Next.
  • Fill in the blanks and click Next.

The FileZilla gathers all of the necessary information and performs a test connection to identify any errors. As a result, if there is no error status, the issue is most likely on the remote site to which you are attempting to connect.

Enter Correct Login Information

The credentials used to log in to the website are frequently different from the credentials used to log in to the file transfer connections. Gather the correct login credentials for your SSH, FTP, or SFTP connection details from your hosting provider.

Limiting the Number of Server Connections

You can reduce the possibility of FileZilla failing to connect to your server by limiting the number of live connections. With your site manager’s permission, you can limit the number of connections. As a result,

  • To begin, go to Site Manager and click Files.
  • Select the most appropriate connection data.
  • Check your transfer settings once more.
  • Finally, press OK.

Changing the port number to 22

The secured file transfer protocol’s default port number is 22. If you use a port connection number other than 22 in Filezilla, you may receive the error message -could not connect to server. To fix the problem, alter the port number in the FileZilla client software to 22.

Switch to the Passvise Tranfer Mode

FTP clients, as previously stated, can transfer files in both active and passive modes. Active mode can sometimes cause connectivity issues, depending on the configurations. Because active mode is the default transfer mode, you must manually switch to passive mode. Passive transfer mode, in general, reduces connectivity issues and is firewall-friendly.

For changing transfer mode, follow these steps

  • Select the Transfer Settings option in the Site Manager.
  • Select the Passive option.
  • Click OK to continue.

Filezilla is an FTP/SFTP application and free open source software that is used to transfer files between a remote site and a local computer. However, your server may experience some connection problems from time to time. In most cases, the issue is caused by misconfiguration or login credentials. Apart from these, there are several important causes that we will overlook.
