vsftpd FTP server on Ubuntu 20.04

I am experimenting with this tutorial to setting up an FTP server on an Ubuntu 20.04 instance and seeing if I can push a CSV file to it from a Windows 10 instance with Python.

On the linux side I have the settings exactly like the tutorial states when going thru modifying the vsftd config file with nano:

listen=NO
listen_ipv6=YES
anonymous_enable=NO
local_enable=YES
write_enable=YES
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
chroot_local_user=YES
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
rsa_cert_file=/etc/ssl/private/vsftpd.pem
rsa_private_key_file=/etc/ssl/private/vsftpd.pem
ssl_enable=YES
user_sub_token=$USER
local_root=/home/$USER/ftp
pasv_min_port=30000
pasv_max_port=31000
userlist_enable=YES
userlist_file=/etc/vsftpd.user_list
userlist_deny=NO

On the client side which is a Windows 10 machine on LAN with the Ubuntu instance I have this Python file to try and push the CSV file to the FTP server running on the Ubuntu instance. I am sort of lost on what I would use for the FTP server authentication as well as the port number to specify that the FTP server is running on.

Python 3.9 from Windows 10:

from ftplib import FTP


FTP_HOST = "192.168.0.105"
#FTP_PORT = 7021
FTP_USER = "ben"
FTP_PASS = "ben"

print("I'm working...")
ftp = FTP()
#ftp.connect(FTP_HOST, FTP_PORT)

ftp.connect(FTP_HOST)
ftp.login(FTP_USER, FTP_PASS)

# local file name you want to upload
filename = "madison_office_2020.csv"
with open(filename, "rb") as file:
    ftp.storbinary(f"STOR {filename}", file)

ftp.quit()

In the Python script I have the port number commented out and the username/password is the user Ubuntu Linux user currently running on the Linux instance. Any tips appreciated this is the traceback that almost seems like a file or directory permissions error. Any tips appreciated not a lot of Linux wisdom here on how to verify file permissions.

Traceback (most recent call last):
  File "C:\Users\bbartling\Desktop\ftp_client\client_side_push.py", line 20, in <module>
    ftp.storbinary(f"STOR {filename}", file)
  File "C:\Python39\lib\ftplib.py", line 498, in storbinary
    with self.transfercmd(cmd, rest) as conn:
  File "C:\Python39\lib\ftplib.py", line 393, in transfercmd
    return self.ntransfercmd(cmd, rest)[0]
  File "C:\Python39\lib\ftplib.py", line 359, in ntransfercmd
    resp = self.sendcmd(cmd)
  File "C:\Python39\lib\ftplib.py", line 281, in sendcmd
    return self.getresp()
  File "C:\Python39\lib\ftplib.py", line 254, in getresp
    raise error_perm(resp)
ftplib.error_perm: 550 Permission denied.

One last note is this directory does exist. /var/run/vsftpd/empty I just dont know how to check user permissions for this directory. Try this below I probably messed it up even worse, not a lot of wisdom here any tips appreciated:

sudo chown -R ben: /var/run/vsftpd/empty
sudo chown -R ben /var/run/vsftpd/empty
sudo chown -R 755 /var/run/vsftpd/empty

Now if I try and check permissions, not sure if this is correct way with just ls -al this will give me ls: cannot open directory '.': Permission denied
