Your server is working and assorted routers/firewalls have been correctly configured for explicit FTP over TLS as performed by this test. However there have been warnings about compatibility issues, not all users will be able to use your server.
For maximum compatibility, consider resolving these warnings.

If someone tells me what can go and what i am doing wrong ?
i can throw files using filezilla, but only to the folder wsalkowski.cba.pl
whether the problem is lack of access to the path /wsalkowski.cba.pl from the ftp client arduino? That is, the file with the default sd card is thrown to the root folder /, which does not have permission chmod?
please help me , and sorry to my english

Let's try to change your FTP server. It's could be problem in server if you log into your FTP.
