RDM Connection Error: "No match for kex algorithm

Hello everyone,
I encountered an issue with my Remote Desktop Manager (RDM) after a recent crash caused by a hard reboot of my computer. Thanks to the assistance of @David Hervieux, I was able to recover my online database successfully. However, I now notice that some settings have reverted to their defaults.
Specifically, when attempting to connect to my Cisco switches, I encounter the following error message:
"No match for kex algorithm:
Client sent: curve25519-sha256,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256,ext-info-c,ext-info-c
Server sent: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1"
I followed the instructions provided in the guide at the following link: [insert URL from original message]. However, the issue persists even after attempting the recommended configuration changes.
Could you please advise me on the next steps I should take to resolve this connection error?
Thank you in advance for your assistance.
Best regards,
