Tis not the key that is having problems, looks like you are having 
problems with possibly AES > 3DES type of configuration.  Time to edit 
that file everybody forgets about /etc/ssh/ssh_config (notice the 
missing d, this is your actual client configuration file, not the 
servers configuration file) you'll see the ciphers config already 
pre-appended, sometimes it's not commented out, you can comment it out 
and let the server select the cipher.  If that still doesn't work, you 
can contact them to see which ciphers they enforce and then enforce that 
for your specific server with the cipher config.
