[BUG] - Ftp with TLS (native-tls) Not working

[c60cb859]

Description

When copying the example from https://github.com/veeso/suppaftp#ftp-with-tls-native-tls the first unwrap errors with status: NotLoggedIn

Steps to reproduce

1. cargo new ftps_test
2. cd ftps_test
3. cargo add suppaftp -F native-tls
4. Copy example to main.rs
5. cargo run

This gives me:

% cargo run
warning: unused import: `TlsStream`
 --> src/main.rs:1:42

1 | use suppaftp::native_tls::{TlsConnector, TlsStream};
  |                                          ^^^^^^^^^
  |
  = note: `#[warn(unused_imports)]` on by default

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Expected behaviour

I would assume I could expect the unwraps and the assert to not give an error

Environment

• OS: Arch Linux
• Architecture: x86
• Rust version: 1.70
• library version: 5.2.0
• Protocol used: FTPS
• Remote server version and name: test.rebex.net (not sure what they are running)

Additional information

It could very well be me that does something wrong

I have now tried with the suppaftp-cli, getting the same Not logged in error

% suppaftp -V
suppaftp 5.2.0 - developed by Christian Visintin <christian.visintin@veeso.dev>
>> CONNECT+S test.rebex.net:21
Failed to setup TLS stream: Invalid response: [530] 530 Not logged in.
>> LOGIN
Can't perform command: you must connect to remote first

looks like it is working without TLS

% suppaftp -V
suppaftp 5.2.0 - developed by Christian Visintin <christian.visintin@veeso.dev>
>> CONNECT test.rebex.net:21
Failed to set transfer type to binary: Invalid response: [530] 530 Not logged in.

It might actually be the servers TLS configuration that is wrong

[veeso]

yeah, the rebex server hasn't been working for a while
