FTPS with TLS not working

[picrap]

I'm no FileZilla expert, so my first question would be: are you sure you're not confusing FTPES with FTPS?
Also, we have a problem with some servers, and in some case the SSL negociation just fails, and until here we could not find why (see issue #32).

I don't even know the difference between FTPES/FTPS, I thought they both mean SSL/TLS connection, versus SFTP which is an SSH based FTP connection.

Luckily your link led me to the solution to my problem, I noticed the extra available SslProtocols in that post and it turns out Tls12 works with my server.

Thanks. :)

FTPES is an explicit SSL, which means that the connection starts on a clear command channel, and then, after a specific command, switches to SSL.
FTPS requires the channel to be open using SSL from the beginning.
Anyway, good to know you solved your problem :)

Thanks for the explanation and the quick responses.
