unable to choose crypto

What does this error mean? I have been seeing this for SFTP connections.

adriane27 Are you devices configured to support SSH? SCP?

I'm not sure where that error is coming from- is that on the client or server? What do the logs look like?

My best guess is that when a client starts SSL, he sends a list of acceptable ciphers. The server also has a list of acceptable ciphers. The server looks at both lists, and chooses which cipher will be used. If neither list has a common cipher, the connection cannot continue.

Have you removed lots of cipher choices from both client and server?

It's true!

When the client tries to connect to the server with unaccepted ciphers, the connection is closed with this error

What SFTP software are you using? Are you able to show us a screenshot of the error and a screenshot of your Encryption tab on Serv-U?
