SecureCrt [No compatible key exchange method]

用SecureCrt连接腾讯云的服务器，报错

Key exchange failed.
No compatible key exchange method. The server supports these methods: curve25519-sha256,
curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,
diffie-hellman-group-exchange-sha256

先使用webSSH连接进去，修改配置文件

vim /etc/ssh/sshd_config

注释掉这一行

重新启动服务

systemctl restart sshd

再次用SecureCrt连接，然后就可以了。
