CatTools: Connect failed:(30044) No available encryption algorithms match with the server.

Question

I can't backup the config, which show a message "Connect failed:(30044) No available encryption algorithms match with the server." 
 But I can ssh the device via the right click menu: Telnet/SSH to device 
 
 May I know what is the problem?

It's a mismatch in ciphers between the node and CatTools. 
 I don't use CatTools but we see very similar issues with NCM and what we have to do is downgrade the default cipher in use on some of our nodes. Once NCM is caught up, then we can revert to the better cipher. Anyway, see here: https://solarwindscore.my.site.com/SuccessCenter/s/article/Kiwi-Cattools-Failed-to-connect-Reason-30044-No-available-encryption-algorithms-match-with-the-serverKiwi-Cattools-Failed-to-connect-Reason-30044-No-available-encryption-algorithms-match-with-the-server?language=en_US for a resolution which states to "contact the dev team".
