Some firewalls and routers block the second connection by default, which would prevent FTP from working. 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. 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. 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. If this happens, it’s usually caused by either an outdated version of FileZilla, or because the firewall or router on your computer has trouble with TLS (a form of encryption) for FTP connections.įirst of all, make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 To see a more detailed answer customized for you, type your domain name here:
