This shows that the FTP connection itself can be established, but the connection fails when trying to enable encryption. This is usually caused by filtering on your network or at your ISP.
There are a few ways you can work around this:
- Go into the FileZilla settings and disable encryption (use “Plain FTP”).
- Use a VPN to bypass the filtering/restrictions on your network.
- Contact your network administrator or ISP and ask them with FTP over TLS doesn’t work.
