FTPS Connection Issue

Hello. Recently i switched from SFTP to FTPS/TLS connection. Dopus was working over SFTP perfectly fine but now i'm having troubles with TLS. It's super slow, takes too long to load directory listing.

Passive mode is selected and still not working properly.

Does the FTP log say anything about errors or timeouts?

This is the FTP log when i attempt to connect or take an action:

211 End
200 Always in UTF8 mode.
200 Switching to ASCII mode.
257 "/" is the current directory
227 Entering Passive Mode (......).
150 Here comes the directory listing.
**** RDIR NO FD_CLOSE Response from Server ****
29508 bytes received in 71.172 seconds (0.0 Kbytes/sec)
226 Directory send OK.
**Opening Connection **
220 Welcome to the FTPS server.
234 Proceed with negotiation.
331 Please specify the password.
230 Login successful.
200 PBSZ set to 0.
200 PROT now Private.
200 Switching to ASCII mode.
257 "/" is the current directory
250 Directory successfully changed.
257 "/....." is the current directory
250 Directory successfully changed.
257 "/......" is the current directory
227 Entering Passive Mode (.....).
150 Here comes the directory listing.
257 "/Test" created
227 Entering Passive Mode (....).
150 Here comes the directory listing.

"NO FD_CLOSE Response from Server" indicates the server isn't closing the data connection properly.

Trying with passive mode off (if it's on now) is also worth a try. Which way works best depends on the scenario.

Unfortunately didn't work.
