# delete deviceconfig system ssh
# set deviceconfig system ssh ciphers mgmt aes256-ctr
# set deviceconfig system ssh ciphers mgmt aes256-gcm
# set deviceconfig system ssh default-hostkey mgmt key-type ECDSA 256
# set deviceconfig system ssh regenerate-hostkeys mgmt key-type ECDSA key-length 256

Hello

Are you using putty? The older version of putty will not support this configuration.
Please use the latest version of putty, or teraterm or secure CRT.
