The problem is that your server, or some firewall or NAT router in front of the server, is not properly configured for FTP over TLS.

Contact your server administrator or server hosting provider for assistance to have the server configuration fixed.

I take care of my server..

TLS Encryption Support : optional

what port(s) using the TLS..?

Allow incoming TCP ports in csf -> ConfigServer Security & Firewall
TCP_IN = 20,21,22,25,53,80,110,143,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096

Allow outgoing TCP ports
TCP_OUT = 20,21,22,25,37,43,53,80,110,113,443,587,873,2086,2087,2089,2703

FTP over TLS Explicit uses the same ports as Plain FTP.

FTP over TLS Implicit uses port 990 by default, but Implicit is never attempted automatically by FileZilla.

You need to allow a range of ports for the data connection.

I have the same problem.

I backed out v3.10 and re-installed 3.7.0.1 and it still works fine.

Do I need to tell FTP site managers to change their configuration so that I can use the latest version of Filezilla client?

I am not a networks guy, but just curious. Is requiring server support for TLS something that was a planned part of v3.10 but was not in v3.7 ?

Filezilla client v3.9.0.6 also works where 3.10.0.1 and 3.10.0.2 do not

FileZilla does not REQUIRE FTP over TLS. It asks the server for TLS support and, if server says "Yes", attempts to use it. Unfortunately many servers say "Yes" but mean "Not really".

For me, the issue was Kaspersky Internet Security 2016.
It caused FileZilla to throw the following errors, while attempting to complete the connection / pull a directory listing from my server.

In Kaspersky 2016, the setting is located under Settings > Additional > Network > Encrypted Connections Scanning > "Scan Encrypted Connections".

While enabled, this causes FileZilla issues connecting with "Require explicit FTP over TLS":
/-----------------------------------
Command: LIST
Response: 150 Opening BINARY mode data connection.
Response: 226 Transfer complete.
Error: GnuTLS error -110: The TLS connection was non-properly terminated.
Status: Server did not properly shut down TLS connection
Error: Transfer connection interrupted: ECONNABORTED - Connection aborted
Error: Failed to retrieve directory listing
\----------------------------------

The temporary work-around is to disable "scan encrypted connections" .. or merely allow FileZilla to communicate without encryption which is never a smart choice.
