New description:

 This is happening with two SFTP accounts. Both worked fine for many months
 and as recently as last week.

 No settings have been changed. Both accounts can be accessed normally,
 with no issues, using other FTP client apps. With CyberDuck I receive this
 error message:


 {{{
 Unable to reach a settlement: [diffie-hellman-group14-sha1, diffie-
 hellman-group1-sha1] and [diffie-hellaman-group-exchange-sha256]. The
 connection attempt was rejected. The server may be down, or your network
 may not be properly configured.

 }}}

 Note: I don't know who diffie-hellman-group is. These don't appear to be
 certificates for me or my hosts.

 I did contact the hosting provider. It was established that normal
 connection is possible by using other FTP clients.

 Thank you.
