Who to connect in filezilla with provided ftp credentials ?

Hello,
From my client I received ftp account and sample listing, that credentials are valid:

ubuntu@ip-CLIENT_IP:~$ ftp CLIENT.REMOTE.SERVER
Connected to CLIENT.REMOTE.SERVER.
220 ProFTPD Server (ProFTPD) [CLIENT.SERVER.IP]
Name (CLIENT.REMOTE.SERVER:ubuntu): SERVERUSER
331 Password required for SERVERUSER
Password:
230 User SERVERUSER logged in
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls
200 PORT command successful
150 Opening BINARY mode data connection for file list
-rwxrwxrwx 1 SERVERUSER psacln 692 Mar 9 21:29 Dockerfile-composer
-rwxrwxrwx 1 SERVERUSER psacln 508 Mar 9 21:29 Dockerfile-nginx

Code (markup):

I have not worked with ftp last several years and maybe I forgot something, but I opened filezilla and tried to connect
with provided credentials and got error :

I got error :

Status: Connecting to CLIENT.SERVER.IP:22...
Status: Connection established, waiting for welcome message...
Response: SSH-2.0-OpenSSH_7.6p1 Ubuntu-4ubuntu0.3
Error: Cannot establish FTP connection to an SFTP server. Please select proper protocol.
Error: Critical error: Could not connect to server

I entered parameters :

Are some of them wrong ? Which valid?

Thanks!

 

The reason is because the server runs on Secure FTP (SFTP) instead of FTP. Normally, ftp runs on port 21 and SFTP runs on port 22. In your screenshort, you are using port 22 but connecting with FTP.

To fix it, select SFTP in the protocol dropdown. That should work.
