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.
