Thank you for a very helpful and useful post. I am so excited to take the Deep Learning course, but I still have a problem though.
I was following your instructions step by step. The only thing that was different, the private_key file was not in .vagrant folder, but in .vagrant.d (.vagrant was also created, but is empty).
But when I try to connect with PuTTY, it won’t work throwing an error “Network error:Connection refused”.
After googling it, I found threads that changing the network settings of VM from NAT to Bridged might help, but it didn’t. Do you have any ideas what I am doing wrong?
