Hi

I do have SFTP which does work, but I have to approve my device IP address every 28 days through my provider. It is usable.

I guess the FTP library of FileZilla will work with TLS session reuse, but the Android FTP library does not!

Thanks for trying.
Chris

I just tried the Android app Total Commander with the FTP plugin. I could get FTP over TLS to work. It must use a different FTP library!

If would be great if AndFTP could do FTP over TLS.

They might use either a native library or undocumented Android API to get SSL session and re-use it. We've tried such way (not documented/supported APIs) but it's quite difficult to support officially as it could be broken at anytime for some reason. If it happens, I'm not sure what we could answer to customers... We will have a look anyway.

Hi,
There is a quite simple but must be implemented in both the server (FileZilla) and the client (Lysesoft).

1. For the server, uncheck the option "Force PROT P to encrypt file transfers when using FTP over TLS" (bottom "FTP over TLS settings"

2. For AndFTP client, in "Expert/specific FTP settings", set "FTPS data channel security" "clear".

Both changes must be made

This is a work-around and a more definite solution still needs to be developed and implemented.
