Fatal error: Host key verification failed.

Hi, I am confused about this error, can u spare some time to help me?

const FTPS = require('ftps')
const ftps = new FTPS({
	host: '192.168.xx.xx',
	username: 'xx',
	password: 'xx',
	protocol: 'sftp',
	port: 22,
})

ftps.cd('/export/wxsq/resource/fd/h5/for-fonts-server').addFile(__dirname + '/aa.css').exec(console.log);

Error:

null { error: 'cd: Fatal error: Host key verification failed.\r\nput: /Users/ruanjiawei/Desktop/ftptest/aa.css: Fatal error: Host key verification failed.\r\n',
  data: '' }

set ‘autoConfirm: true’ in config. that’s helped me

I use Windows7 for now, and run the terminal as admin.

I mean, when I input yes, though it gave me a hint like that, but it made no effect, I can still login into server.

I just tried ssh again and input no, and got Host key verification fail finally. Now I see, maybe running my script the low level functions answered a no automatically for me?And it just need a retry?😃 That’s all I guess.
