FTP connection problem

Sometimes while accessing FTP you receive following error:

error: 14:15:20    Response:    421 Sorry, cleartext sessions are not accepted on this server.
14:15:20    Error:    Could not connect to server

Above error indicates a server connection/permission problem. Particular server (running on port 21) is expecting  to make a FTPS connection (SSL/TSL) to it.
FTPS make login connections encrypted so they are not plain text, but then send the data after the login in the clear.In order to solve above problem follow following 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.
