transfer files to FTP Implicit TLS

Question

I am trying to transfer files to a FTP implicit TLS server using python. I can connect to the server, I can upload the file, but at the end, I am having an exception.

Here is my code. First part is the class.

import ftplib
import ssl

class ImplicitFTP_TLS(ftplib.FTP_TLS):
    """FTP_TLS subclass that automatically wraps sockets in SSL to support implicit FTPS."""

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self._sock = None
        #self.verify_mode(False)

    @property
    def sock(self):
        """Return the socket."""
        return self._sock

    @sock.setter
    def sock(self, value):
        """When modifying the socket, ensure that it is ssl wrapped."""
        if value is not None and not isinstance(value, ssl.SSLSocket):
            value = self.context.wrap_socket(value)
        self._sock = value

The second part is to connect and send the file.

ftp_client = ImplicitFTP_TLS()
ftp_client.connect(host='ip_address', port=990)
ftp_client.login(user='username', passwd='my_password')
ftp_client.prot_p()
ftp_client.dir()
tmp_file_name = "my_file.csv"
tmp_file = open(tmp_file_name,'rb')
destination_path = '/my_destination_file.csv'
remote_path, remote_file_name = os.path.split(destination_path)
ftp_client.cwd(remote_path)
ftp_client.storbinary(f'STOR {remote_file_name}', tmp_file)

The file is transferred, but i have en error like this : "SSLEOFError: [SSL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol (_ssl.c:2702)"

That resulted from '/usr/lib/python3.10/ssl.py' (3rd line which says 'shutdown'):

def unwrap(self):
    if self._sslobj:
        s = self._sslobj.shutdown()
        self._sslobj = None
        return s

Does anyone have a solution or suggestion for this problem ? thanks.
