CentOSで、 vagrant upしようとすると、

[root@{server name}] myProject]# vagrant up
All Plugin Dependencies already installed

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

のようになり、default: SSH auth method: private key のところでタイムアウト
してしまいます。

何度かvagrant destroy してみても変化なく、myVM.vboxを編集してcable="true"を追記してもうまくいきませんでした。　自分のmac上では、VirtualBox, Vagrant共にサーバ上と同じバージョンの組み合わせでうまく動きました。　

どうすれば無事sshできるのでしょうか。これが解決しないと先に進めず、大変困っています。
どなたかご教示いただけませんでしょうか。

[root@{server_name} myProject]#vagrant -v
Vagrant 2.2.3

[root@{server_name} myProject]#

のような環境です。VirtualBoxは5.2が入っています。
