TLS Encryption

[cramsey]

When we create FTP accounts, we advise our clients to use your client. This allows the customer to use an FTP session with TLS encryption.
A new client downloaded the current version of FileZilla and set it up per our standards (using TLS encryption). When the customer ran the connection, they were able to connect, but received the following:

Status: Server did not properly shut down TLS connection
Error: Transfer connection interrupted: ECONNABORTED - Connection aborted
Response: 226 Directory send OK.
Error: Failed to retrieve directory listing

The customer was continued to be logged in, but the directory listing was not available.

Broken server. You need to upgrade to a fixed/better server. See ​http://forum.filezilla-project.org/viewtopic.php?f=2&t=7688 for details.

I don't like to repeat myself, so I just refer you to my previous reply which still holds.
