Hi David,   I am not sure about active/passive mode. I used FileZilla v3.67 @ win10 / ubuntu. The mode "implicit FTP" does not work with any network (so I guess, it's not supported by the FTP server), but "explicit FTP" also doesn't work. Plain FTP (without encryption) and SFTP (SSH) works fine.   FileZilla has two "explicit FTP" modes: "Use explicit FTP over TLS if available" and "Require explicit FTP over TLS".   Using these modes, I get the following error messages, with "Use explicit FTP over TLS if available":   Status: Resolving address of DOMAIN.TLD Status: Connecting to XXX.XXX.XXX.XXX:21... Status: Connection established, waiting for welcome message... Status: Insecure server, it does not support FTP over TLS. [.. continues with plain FTP ..]   with "Require explicit FTP over TLS":   Status: Resolving address of DOMAIN.TLD Status: Connecting to XXX.XXX.XXX.XXX:21... Status: Connection established, waiting for welcome message... Response: 220-FTP server ready. Response: 220 This is a private system - No anonymous login Command: AUTH TLS Response: 504 Command not implemented for that parameter Command: AUTH SSL Response: 504 Command not implemented for that parameter Error: Critical error: Could not connect to server And as expected, because probably not supported by the FTP server, I get this with "Require implicit FTP over TLS":   Status: Resolving address of DOMAIN.TLD Status: Connecting to XXX.XXX.XXX.XXX:990... Status: Connection attempt failed with "ETIMEDOUT - Connection attempt timed out". Error: Could not connect to server   ... View more
