Erro UNREACHABLE e Permission denied Vagrant

Estou tentando configurar a VM pelo vagrant, mas da erro 'UNREACHABLE!', fiz os comandos

ssh-keygen -t rsa
ssh-copy-id -i vagrant_id_rsa.pub vagrant@172.17.177.40

Mas apareceu isso no terminal:

/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "vagrant_id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
vagrant@172.17.177.40: Permission denied (publickey).

Obs: utilizo o Ubuntu 19.04
