What is the valid kex algorithm for your server? If you don't know, you can set all kex algorithms.

{
 "kex": [
      "ecdh-sha2-nistp256",
      "ecdh-sha2-nistp384",
      "ecdh-sha2-nistp521",
      "diffie-hellman-group-exchange-sha256",
      "diffie-hellman-group14-sha1",
      "diffie-hellman-group-exchange-sha1",
      "diffie-hellman-group1-sha1"
 ]
}

Thank you answer.
Still not working.
Is there a problem with the setting other than the kex algorithm?

[liximomo]

Try v1.1.0. It should be fixed.
