When you have problems connecting to your Cisco ASA and see following error message:
Cisco ASA Failed to connect to the host via ssh: Unable to negotiate with 192.168.100.204 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1\r\n”,
Workaround to change ssh diffie-hellman group:
conf t ssh key-exchange group dh-group14-sha1 exit wr mem
Now you can try it again and able to connect to the ASA.
