ITL_FTP_RW - error 553 - can't open that file: is a directory

Good evening all,
I open this post to show you an error, i get when iuse the FB, ITL_FTP_FileRW.
I use PLCnext Engineer v.2022.3, and the firmware of the PLC AXC F 3152 is updated to the latest version 2022.5.
I am trying to copy the files generated by my datalogger into an our Server.
I attached the screenshots of the FBs used, and the error I receive, what could it depend on?
Do I use the IPC_Socket FB, or do I have to use the TCP_SOCKET FB?
FTP ERROR.PNGFTP_DIAG.PNGThanks for those who want to help me.

Here is the answer from the PLCnext Engineer support team:
The error comes from the server and I am assuming that the file name is not permitted or is not even specified on the FB. If you have any further questions, please contact the app owner directly from the plcnext store. The library download also contains examples.
