FTP Problem: SSL/TSL Security

Yahoo is my web hosting provider. Today I received the following connection error when using Cyberduck:

"421 Sorry, cleartext sessions are not accepted on this server. Please reconnect using SSL/TLS security mechanisms."

Is this an application error or do I need to make settings changes?

Thank you, Richard
