I am trying to upload a .zip File with my Java application to an FTP server using the Apache Commons Net FTPSClient.

Things I checked:
- Connection to FTP Server is working
- Login is successful
- Directory on FTP Server is created successfully
- Empty .zip File with correct name is created on FTP Server
- Permission on remote Directory is 755 (writing possible)
- Both local and remote File Paths are correct and local file exists
Anyone know how to solve the error?
