FileZilla Cannot Connect to Server: Troubleshooting Guide
Encountering connection problems with FileZilla can be frustrating. This article provides a step-by-step guide to troubleshoot and resolve common issues preventing FileZilla from connecting to your server.
Basic Checks and Network Configuration
Before diving into more complex solutions, ensure the basics are covered:
- Verify Server Details: Double-check the hostname, port number, username, and password. Even a minor typo can cause connection failure. Remember that default FTP port is 21, and SFTP port is 22.
- Check Internet Connection: Ensure your computer has a stable internet connection. Try browsing the web to confirm.
- Firewall Interference: Your firewall might be blocking FileZilla. Add FileZilla as an exception in your firewall settings. On Windows, go to "Windows Defender Firewall" -> "Allow an app or feature through Windows Defender Firewall."
- Router Issues: Restart your router. This can resolve temporary network glitches that might be hindering the connection.
Advanced Troubleshooting Steps
If the basic checks don't resolve the issue, proceed with these advanced steps:
Passive Mode Configuration
- Open FileZilla and go to "Edit" -> "Settings".
- Navigate to "Connection" -> "FTP" -> "Passive mode".
- Select "Use the server's external IP address instead". In some cases, selecting "Fall back to active mode" might also help.
- Click "OK".
Passive mode is often necessary when connecting from behind a router or firewall. Active mode (the default) requires the server to initiate a connection back to your client, which firewalls often block. Passive mode has the client initiate both connections.
Explicit FTPS and SFTP Considerations
If you're using FTPS (FTP over SSL/TLS) or SFTP (SSH File Transfer Protocol), ensure you're selecting the correct protocol in FileZilla's connection settings. For FTPS, choose "Require explicit FTP over TLS" in the "Encryption" dropdown. For SFTP, choose "SFTP - SSH File Transfer Protocol". SFTP connections require an SSH server running on port 22 of the remote server. Contact your hosting provider if you are unsure which protocol to use.
Contacting Your Hosting Provider
If you've exhausted all troubleshooting steps and FileZilla still cannot connect, contact your hosting provider. They can verify if there are any server-side issues or specific configurations required for your account.
