Aula 6, Too many authentication failures for vagrant

Estou tentando rodar o playbook depois de "matar" a maquina Wordpress, mas estou esbarrei com um erro de Too many authentication.

Fiz um teste rodando um ping na maquina:

 ansible wordpress -m ping -vvv -i hosts

Aqui parte do retorno:

172.17.177.40 | UNREACHABLE! => {
    "changed": false, 
    "msg": "Failed to connect to the host via ssh: Received disconnect from 172.17.177.40 port 22:2: Too many authentication failures for vagrant\r\nDisconnected from 172.17.177.40 port 22\r\n", 
    "unreachable": true
}

Poderiam me ajudar a resetar o número de conexões ssh?
