Filezilla and TLS

Hi All

I have searched all forums for a solution and still cannot find one

I have Debian 9 with the following setup:
The Perfect Server - Debian 9 (Stretch) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.1
How to install PHP 7.x as PHP-FPM & FastCGI for ISPConfig 3.1 with apt on Debian 8 and 9
Securing ISPConfig 3.1 With a Free Let's Encrypt SSL Certificate

Everything is working ok until I use Filezilla 3.40.0 when connecting I am now getting the following error
Unknown Certificate
The server's certificate is unknown. Please carefully examine the certificate to make sure the server can be trusted.
Certificate info:
Valid from: 08/11/2018 16:35:17
Valid to 06/02/2019 16:35:17 - Certifcate expired!

Session details:
hostname does not match certificate

Filazilla shows this:
2019-02-19 08:35:09 5904 1 Command: AUTH TLS
2019-02-19 08:35:09 5904 1 Response: 234 AUTH TLS OK.

2019-02-19 08:35:19 5904 1 Error: GnuTLS error -110: The TLS connection was non-properly terminated.
2019-02-19 08:35:19 5904 1 Status: Server did not properly shut down TLS connection
2019-02-19 08:35:19 5904 1 Error: Could not connect to server

Plain Ftp connects ok, its only when I use explicit FTP over TLS if available

Any Ideas on how to get Fillezilla working with TLS

Cheers

Hi Till thanks for yor reply
after redoing https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/
I am only getting problems with Filezilla error shown is:
10:02:36 Status: Initializing TLS...
10:02:36 Status: Verifying certificate...
10:02:36 Error: GnuTLS error -110: The TLS connection was non-properly terminated.
10:02:36 Status: Server did not properly shut down TLS connection
10:02:36 Error: Could not connect to server
WinSCp and SmartFTP connects with no problem, just curious as to why only Filezilla is not connecting
Filezilla Version 3.40.0

Cheers Scorp

 

Hi till
Yes it seams like a problem between that specific FileZilla version and the pure-ftpd version as all the forums I have looked at seam to state the same.
Cheers for your fast replys
