- Plesk for Linux
The following error is shown during an attempt to establish a connection via Filezilla:
CONFIG_TEXT: Status: Connecting to example.com:21...
Response: fzSftp started, protocol_version=8
Command: open "firstname.lastname@example.org" 21
Error: Network error: Connection refused
Error: Could not connect to server
Attempting to connect with SFTP protocol instead of FTPS.
Go to FileZilla > File > Site Manager > New Site, choose the appropriate protocol (FTPS), input the credentials and connect again.
If the issue persists, make sure that all the required ports are opened according to Which Ports Need To Be Opened for all Plesk Services to Work with a Firewall?
Note: SFTP is not supported by Plesk.
