Error 550 when writing maps and files

[Albert2305]

I have a security Cam and I want to save the video's on my Fizilla FTP server.
For this Cam I have created a user with full access (see file below)
When the Cam is logging in, everything is ok, but I got an error on writing.

Testing the user with filezilla client gives no error.

Anyone knows what is going wrong?

Your client tries to create a directory or file inside the home directory set in FileZilla Server. Please check your home directory permissions.

Working again with my Camera and I have stil the problem with creating a map.
The camera has full access on Home directory and the directory for the files.
All my other FTP clients are woring fine (already for several years) and only the camera has a problem.

According to the screenshots the client tries to create a directory that already exists. It doesn't do anything else.
