NppFTP Unable to connect

[Дмитрий Суричев]

Npp 7.9 64
NppFTP 0.30 64
or 0.29.6

I am testing connecting to various FTP servers.
Including to ftp://91.122.30.115/
this server has public access.
I have tried various settings.
Anyway I get
-> TYPE I
Connecting
-> Quit
Unable to connect
Disconnected
-> TYPE I
Connecting
-> Quit
Unable to connect
Disconnected

To any server.
I even began to doubt - does the program have Internet access?
BUT if you select the connection type FTPS, then the server response:
Connecting
[SFTP] Connection failed: Failed to resolve hostname ftp://astral.com.ru ()
Unable to connect
Disconnected

FILEZILLA is the standard as always!

I saw a recommendation in one of your answers:
provide debug information
and where to get it? I would like to see it myself.

Not properly
ftp://91.122.30.115
ftp://ya.ru
right
91.122.30.115
ya.ru

Go to the ? menu in Notepad++, and it has a Debug Info entry.

When I tried with the ftp://91.122.30.115/ URL (by the way, it would have been nice if your “working filezilla” example had actually been to the same site as your “not-working NppFTP” example) – FileZilla gave

Status:	Connecting to 91.122.30.115:21...
Status:	Connection established, waiting for welcome message...
Status:	Insecure server, it does not support FTP over TLS.
Status:	Server does not support non-ASCII characters.
Status:	Logged in
Status:	Retrieving directory listing of "/"...
Status:	Directory listing of "/" successful

With no username or password, using FTP, NppFTP gave

[NppFTP] Everything initialized
-> TYPE I  
Connecting
-> Quit  
220 Welcome to Pineforest.info FTP service.
-> USER   
331 Please specify the password.
-> PASS *HIDDEN*
503 Login with USER first.
Unable to connect
Disconnected

When I changed the settings to give an anonymous username, and ask for a dummy password

When I ran that connection I typed anonymous, it gave:

-> TYPE I  
Connecting
-> Quit  
220 Welcome to Pineforest.info FTP service.
-> USER anonymous  
331 Please specify the password.
-> PASS *HIDDEN*
230 Login successful.
-> TYPE A  
200 Switching to ASCII mode.
-> MODE S  
200 Mode set to S.
-> STRU F  
200 Structure set to F.
-> PWD  
257 "/" is the current directory
Connected
-> CWD /  
250 Directory successfully changed.
-> PASV  
227 Entering Passive Mode (91,122,30,115,135,92)
-> LIST  
150 Here comes the directory listing.
226 Directory send OK.

So NppFTP connected just fine to ftp://91.122.30.115/

So, it works for me.
