Access to localhost was denied 403 on Windows

[krisrandall]

Running this tutoria (day1) l in a large group - all the Mac users successfully see the app at http://localhost:3000/ and all the Windows users (4 of them) instead see "Access to localhost was denied", getting a 403 returned.
This is in Chrome. In other browsers (Water on one machine, Firefox on another) it instead comes up with a blank page, however the favicon icon is displaying.

There is nothing in the terminal output which is suggesting an error to me :

Hi Kris!

We've seen the same report come in on the forums as well. We have prioritized investigation into this internally, and will be working on a solution for you!

In case you haven't seen it, the related forum post is here: https://devcamp.holo.host/mod/forum/discuss.php?d=350#p1316

Turns out that the issue here is that you just have to type in the full url:: http://localhost:3000/index.html Not sure yet why this is required on windows and not linux/mac.

[Connoropolous]

We will update the instructions in the README for windows
