Here is the log from firezilla which was installed only for testing. I bought this program from awesome gpsoftware so i didn't have to use something else.
| Status: | Connecting to 192.168.7.27:21... |

## This is connecting to a proftpd server
The below is with a site saved in the ftp address book:
site name: dns1
connection: standard
username: ftpuser
Password: "saved password"
initial directory:
{{Network tab, rescan directory after change ON, Use PASV (passive) mode ON}}
Opening Connection 192.168.7.27:21
220 ProFTPD Server (PROftpd) [192.168.7.27]
550 SSL/TLS required on the control channel
Connection closed
Below is with all the same settings **EXCEPT**
connection: SECURE TLS EXPLICIT (AUTH TLS)
Opening Connection 192.168.7.27:21
220 ProFTPD Server (PROftpd) [192.168.7.27]
234 AUTH TLS successful
SSL\_connect error 1
TLS/SSL connection to server failed!
Connection closed
\*\* Cannot establish SSL Connection.
Both methods fail using DOPUS. Only sucess is with firezilla quickconnect.

I found something that seems similar to the problem you are experiencing.
[https://serverfault.com/questions/934976/connecting-to-a-ftp-by-tls-fails-from-one-client-but-succeeds-from-the-other](https://serverfault.com/questions/934976/connecting-to-a-ftp-by-tls-fails-from-one-client-but-succeeds-from-the-other) .
At the bottom of the answer there is a link that may help you test your site URL for more specifics .

Still no sucess with DOPUS.

Are you sure port 21 is correct? That's normally the port number for ordinary non-encrypted FTP.
