I have been following the tutorial Install and Configure VSFTPD server on Ubuntu 18.04 LTS but cannot connect when I get to the step of using my browser to connect using ftp://IP address. The response I get is Cannot reach this page. I have an SSH connection for both root and my UserName which can reach the website. I can ping the website so I conclude that vsftpd although showing started is in someway misconfigured. I did get an error code 2 INVALID ARGUMENT on my first attempt but I corrected the faulty argument in the vsftpd.conf. How can I find out what is stopping vsftpd from responding?
