Ansible dá erro ao tentar o SSH | Vagrant: gerenciando máquinas virtuais

Olá!

Estou tentando rodar o comando na minha VM Ubuntu

ansible-playbook -i ./configs/ansible/hosts ./configs/ansible/playbook.yml

Mas ele sempre está trazendo essa mensagem enorme:

fatal: [192.168.234.137]: UNREACHABLE! =>

Na VM "mysqlserver" já adicionei a chave pública no arquivo authorized_keys:

vagrant@ubuntu-bionic:~/.ssh$ pwd
/home/vagrant/.ssh
vagrant@ubuntu-bionic:~/.ssh$ cat authorized_keys 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDK8BZd07ILn4Sc/NOye+JCtmWT+e+iagH7JP0bIKsJHK5BT/vtz4KYC8QZjjpXcCdihC8NHCaptay3g7NBPvx7RQOt/NSkMoXAHLq+vPS7kotWKroCJA3A2t5U+KHmR6MIfp0GkmulZPWYFJG7JmR7aQFdCjWw5kIeGdN4SvPYB3AKlQuWgi5FODMdhsdjtm1O1+ksV2k3lYHG1192M5MfDFS6hEZuk0lksqnTLndsnyFfwxvk52+2S9SaFLZS0dE+vw1JEMLiuoH0J2vT0v7+0r9D+5WTofEEED+V7IbO6Ws+Ah3g6pCN/JNIo5hIClyMZ13U7pamDa1xAEx6NoO3 vagrant

Meu arquivo hosts está assim:

[mysqlserver]
192.168.234.137

[mysqlserver:vars]
ansible_user=ubuntu
ansible_ssh_key_file=/home/renan/ambiente_dev/bionic64/ubuntu_key
ansible_python_interpreter=/usr/bin/python3
ansible_ssh_common_args='-o StrictHostKeyChecking=no'

O arquivo "playbook.yml" está igual ao da aula.

Este é o Vagrantfile:

Vagrant.configure("2") do |config|

        config.vm.box = "ubuntu/bionic64"

        config.vm.define "mysqlserver" do |mysqlserver|            
            mysqlserver.vm.network "public_network", ip: "192.168.234.137"        

            mysqlserver.vm.provision "shell", inline: "cat /vagrant/configs/ubuntu_key.pub >> .ssh/authorized_keys"    
        end
end

O que mais devo fazer para conseguir rodar o comando para rodar o ansible?
