ProppFrexx ONAIR User-Forum

Normal ftp works like a charm. That's what i have used so far. The data is indeed not that relevant but my ftp login credentials for my website are and they will be transferred unencrypted too i'm afraid
I shall contact my provider to see if they have any idea left how to make this work, else it would only be ftp. I'll let you know.
Thanks for your support and keep going. It's a very nice and rockstable software.

Found a solution to work with FTP over TLS with Proppfrexx and Windows 10

The stateful FTP packet inspection in Windows Firewall will most likely prevent SSL from working because Windows Firewall filter for stateful FTP inspection will not be able to parse the encrypted traffic that would establish the data connection.

To disable stateful FTP filtering so that Windows Firewall will not block FTP traffic, run cmd as administrator and type the following syntax then hit enter:
netsh advfirewall set global StatefulFtp disable

This should do the trick. Worked for me this way

A 4.2.5.0-Beta is out. So ‚Check for Beta-Version…‘ to update. In it optimized the FTPS support which should work out of the box mich easier.
