So this is the first thing the server responds with?

It makes it sound like it wants a "secure command connection". Then you
shouldn't use ftp:// but instead use FTPS://...

Nope. FTP means insecure, unencrypred, plain text connection. It can of course
optionally switch over to a secure connection but it always starts plain text.

Your server response hints that it expects an SSL connection from the start,
so you should use a FTPS:// url (which defaults to port 990).

Good luck!
