Hi,
Sorry for delay answer, hower I recently updated to latest version of library, and still have this issue.
Yes this happen fro every file I'm sending. The funny thing is WinSCP has the same issue. The server is SSH implementation = CoreFTP-0.2.3.
However I cannot change the server, but I started testing other components (paid ones) and they are working. Also FileZilla is working without issue with this server. But this component has the issue.
Regards
Marcin
