Connection Error

When attempting to login to an established session, connection can not be established and error message pops up. Typically when I hit the Login button from the home page, it loads another screen where a connection is established and a password must be entered. I do not have the ability to enter a password because I get the error message during the connection phase. The error message that pops up reads: "Couldn't agree a key exchange algorithm (available: ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256)"

It gives me the option to reconnect but returns to this same message. Any ideas on how to establish connection and resolve this error?

Thank you.

Please attach a full session log file showing the problem (using the latest version of WinSCP).
