FPT connection with SSL\TLS does not work

Good afternoon.

I am unable to connect NetDrive 3 to an FTP server with SSL\TLS.

I’ve already done telnet testing and port 990 is properly open.

I can also connect via FTP (I used WinSCP to test and got a connection).

The only issue is that in WinSCP, it uses TLS/SSL Implicit Encryption, and in NetDrive the option doesn’t appear (I suspect that NetDrive is using SSL/TLS Explicit Encryption and so it doesn’t connect).

Can you guide me?

I use NetDrive 3 in version 3.15.432.

Note: the server in question that I want to connect to the FTP has port 21 blocked for security reasons.

Only the 990 is free for connection.


Thank you for using NetDrive.

Did you check “SSL/TLS”?



Good Morning. Yes! I checked the SSL/TLS option.

However, as I don’t have the option Explicit or Implicit, I suspect that by default it uses Explicit (because to connect to it, port 21 must also be released and as my firewall is blocked for security, so it gives a connection error) .

Could you attach debug log files to figure out?

After setting the log level to VERBOSE, please reproduce the problem and send us the debug log file :

There is no login related credential information in the log files.


I restarted all Services to be able to reset logs and send new ones to you.

When restarting the services, connecting again, changing to VERBOSE and trying to redo the configuration where I had the SSL\TLS connection error, I was able to connect.

For some reason, restarting the NetDrive 3 program solved my problem.

It’s a good news.

If you have any question, don’t hesitate to contact us.
