Sometimes while accessing FTP you receive following error:
[wpfmb type=’error’ theme=2]error: 14:15:20 Response: 421 Sorry, cleartext sessions are not accepted on this server.
14:15:20 Error: Could not connect to server[/wpfmb]
order to solve above problem follow the steps:
1) Login to WHM with root user.
2) Go To : Service Configuration >> FTP Server Configuration
and then check if the setting :
TLS Encryption Support : is configured to read to “Optional”
if not, set the configuration to “Optional”.
Now try to connect via FTP.
You should not receive any error now.
