ssh connection timed out

Não consegui conectar via comand do Windows a máquina bionic. Segui os passos da aula.

1. Gerei as chaves;
2. Inclui a chave publica no .ssh/authorized_keys;
3. Conferi se a chave tinha sido incluida;
4. Olhando no fórum inclui no Vagrantfile a configuração "config.ssh.insert_key = false"; Mas, não consegui conectar com a chave privada e usuário vagrant.

   ssh -i id_bionic vagrant@172.27.187.59

OBS: com o "vagrant ssh" conecto normalmente;

meu vagrantfile:

Vagrant.configure("2") do |config|
    config.vm.box = "hashicorp/bionic64"
    config.ssh.insert_key = false
    config.vm.network :forwarded_port, guest: 80, host: 8089
    config.vm.network "public_network", ip: "172.27.187.59"
end

authorization_keys:

vagrant@vagrant:~$ cat .ssh/authorized_keys
