            # Forwarding SSH and VNC ports on VM. N.B., SSH (22) is already
            # forwarded to 2222. Keeping configuration line in for documentation.
            node.vm.network "forwarded_port", guest: 22, host: 2222, auto_correct: true
        end
end

Please note, if you are using Homestead or a different Vagrantfile format, we may be unable to assist with your issue. Try to reproduce the issue using a vanilla Vagrantfile first.

@mdeepa2285 - Hey! Has this worked on any previous versions of macOS and or Vagrant for you in the past?

[mdeepa2285]

Yes, this worked with previous macos, now we are in the process of upgrading Mac guest OS to high sierra and having this error.

[mdeepa2285]

after commeting out node.vm.hostname = "#{hostname}-q3-1" , getting below error

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

networksetup -detectnewhardware

Stdout from the command:
