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 Code (markup): I entered parameters : https://prnt.sc/u005uz 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.
