FTP error 421

[valentine]

We often come accross an error while using FTP service the error is as follows:

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

The error here arises due to connection/permission issue.Cause when using port 21 the server expecting to establish a secure FTP connection (i.e tries to use FTPS).
As we know that FTPS uses encrypted login connection and do not use plain texxt as FTP uses at that time we experiance the above error.

Below mentioned are the steps to eliminate the above error:

1> Login to WHM.
2> Go to Service Configuration >> FTP Server Configuration
3> After going to the above option check the settings
TLS Encryption Support : is configured to read to “Optional”
If it is not set “Optional” set it to “Optional”.

Now try to connect FTP.Bingo the error is gone!!
