Laravel Homestead挂起了SSH Auth方法

Question

I'm having an issue with Laravel Homestead on Windows 7. When I run vagrant up it's hanging on:

SSH auth method: private key

Not sure why this is. I've tried a number of solutions. Here the auth stuff from my homestead.yaml file:

authorize: C:/Users/Kim.Ward/.ssh/id_rsa.pub

keys:
    - C:/Users/Kim.Ward/.ssh/id_rsa

I have also tried:

authorize: ~/.ssh/id_rsa.pub

keys:
    - ~/.ssh/id_rsa

I've attempted adding:

   config.ssh.private_key_path = "C:/Users/Kim.Ward/.ssh/id_rsa"

and:

config.ssh.username = "vagrant"
config.ssh.password = "vagrant"

I can confirm that virtualisation is enabled and I'm using an i5 6500.

If I check virtual box while the box is booting and I can see in the preview window a login prompt. I can also double click the instance in virtual box and it'll open up and allow me to login but it doesn't look like the set up process is complete.

I am using Virtual Box version 5.1.18 and Vagrant v1.9.1. I have tried with various other minor versions.

Any help would be greatly appreciated. I'm running out of ideas that this point.

Thanks,

Kim
