Hi, The FTP is working fine since we setup the Plesk Linux 9.5 but it's not working suddenly. It shows the below message when we tried to connect: Status: Connection established, waiting for welcome message... Error: Connection timed out Error: Could not connect to server We've checked the firewall setting, there's nothing wrong with it, we don't made any changes on it as well. We've restarted the Apache but still not working. Any idea or suggestions? Thanks.
