00:29:20 Response: 226 Directory send OK. 00:29:20 Response: 150 Here comes the directory listing. I noticed the following difference between normal and SSL/TLS mode in the returned message from the PASV command. But if you enable TLS/SSL for the first connection, the firewall can’t see the contents of it because of the encryption, and it doesn’t know that it should allow the second connection.ĭisabling SSL/TLS fixes this because the firewall can see the contents of the first connection and properly allow the second connection.Īlternately, using SFTP fixes it a different way: Because SFTP only uses a single connection and doesn’t need a second connection at all, your firewall or router setup doesn’t matter. To do so, go to Site Manager in FileZilla ( File > Site Manager) and change encryption type to Only use plain FTP under General tab. When SSL/TLS is enabled, FZ fails to retrieve a directory listing from vsftpd behind NAT. To solve this problem, they examine the commands sent in the first connection to know when to allow the second one. Some firewalls and routers block the second connection by default, which would prevent FTP from working. My Client had the default setting of Connection -> FTP -> Active Mode. The first connection handles commands like “Send me file X” or “Show me the list of files in the Y directory”, and a second connection is then opened to actually send the file or directory listing. After analyzing the situation, it turns out the solution isnt so obvious. What’s the technical reason that FTP with TLS doesn’t work on some firewalls or routers?įTP uses two connections to work properly. If you want or need to continue to use plain FTP for some reason, you can disable TLS encryption.Įach time you want to connect to the server, simply open the Site Manager again and click Connect.
There could be a Firewalls or Antivirus problem, which might be blocking the transfer.

If you still have trouble, the best way to avoid this problem and still keep your password secure is to use SFTP instead of normal FTP in FileZilla. Response: Connection timed out (Failed to retrieve directory listing). When the connection is encrypted with TLS the firewall can't detect the PORT response anymore and therefor not automatically open the assigned port.

If this happens, it’s usually caused by either an outdated version of FileZilla, or because the firewall or router on your computer has trouble with TLS (a form of encryption) for FTP connections.įirst of all, make sure you’re using the latest version of FileZilla (or try another free FTP program like Cyberduck).Īlso try enabling or disabling passive mode (that is, try switching it to the opposite of whatever it’s set to to start with). The TLS connection was non-properly terminated We occasionally hear reports of the FileZilla FTP program getting stuck with a message saying “initializing TLS”, or getting errors soon after connecting, like this:Įrror: Connection timed out after 20 seconds of inactivityĮrror: Failed to retrieve directory listing
