SFTP issue; connection actively refused

Dear SmartFTP support,

I've come across SFTP servers that refuse a connection with SmartFTP. When I tried "SmartFTP - FTPS" under Favourites the same response appeared (see output below).
I'm under the impression that this may be due to recent SFTP changes/enhancements. I did not try version 4.0 yet (see "SmartFTP v4.0.1047 SFTP Problems" thread).

Thank you and best regards,
Atze

I believe that is a network problem. Go to the favorite properties: FTP->Connection->SSL/TLS and under Data Connection set the mode to Clear for both the File Transfer and List Transfer option.

Ok. I've modified the settings as indicated for the "Default Favorite" (only there I could find SSL/TSL under connection). It did not change the behaviour (same in version 4.0.1048.0). Still "No connection could be made because the target machine actively refused it". Please advice.

Try active mode (PORT).
