Different FTP Server?

Hi all!
I have an issue with sending data via my FTP server. I can upload the data, the app considers the files sent, but they never appear in my folder. The process does, however, work if I use the desktop app. I use LiveDrive as a server. Have more of you encountered this problem annd could help me with finding a solution? Alternatively, do you have recommendations on a good and stable FTP server to use?
