Vagrant 'default' issues

I have used Vagrant with PHPStorm for a while now and it used to run fine.

Ever since last week, it's been giving the following error when I try to run my tests:

"The machine with the name 'default' was not found configured for this Vagrant environment"

So I deleted the interpreter from PHPStorm, and tried to re-add it. It gives the same issue. My box name isn't default and never was.

What I don't understand is, I can up and ssh into that box no issues from command line. It seems to me like PHPStorm is trying to do something weird.

Any idea what I can try?
