Hi Karen, I found a reference at Dreamhost wherein a user says that Support hold him that "diffie-hellman-group1-sha1 was recently removed for security concerns". This is 26 days ago. The reference URL is:
https://discussion.dreamhost.com/t/ssh-issue-with-key-exchange-algorithms/68804 It may be that your SSH client does not support newer DH modes, for example group 14. Is there a way you can find out what key exchange modes and ciphers your SSH client supports?
