Upated to OSX 10.10 and am using the latest Cyber Duck. We have been connecting before the OS X update via ftps:// - now when connecting to the same bookmark we are getting a

Ineroperability failure. "Handshake failure. Unable to negotiate an acceptable set of security parameters. Please contact your web hosting service provider for assistance"

220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 2 of 50 allowed.
220-Local time is now 16:10. Server port: 21.
220-This is a private system - No anonymous login
220-IPv6 connections are also welcome on this server.

AUTH TLS
234 AUTH TLS OK.

Deleted the bookmark - checked the FTP - even imported a explicit connection from Filezilla - but it will no longer connect via FTP-SSL just regular FTP. Now Filezilla will connect on explicit FTP over TLS. Contacted hosting and they said just use FileZilla - I DON"T LIKE FILEZILLA - HOW DO I GET MY CYBER DUCKY BACK?

The error message means there is no match in negotiating the SSL ciphers to secure the connection. Can you let me know the server name or IP address which will allow us to look at the ciphers the server supports.

Server name is AHS2.R4L.com - IP is 198.27.70.84

Hosting says you are wrong because we have proven that the FTP works with encryption with the FileZilla connection. Ciphers are secure. They say its a bug in Cyber Duck and or incompatibility issue with Mac OS X 10.10

I just want my Cyber Ducky back on FTP-SSL

Trying to reproduce the issue here, the handshake is successful with TLS_RSA_WITH_AES_256_CBC_SHA as the negotiated cipher.
