Cannot preview Octopress generated website

I am new to Jekyll and I am trying to build a blog using static pages with Octopress.

rake is generating the site correctly without any errors but when I try to preview the site, depsite that the server starts without any error

>>> Compass is polling for changes. Press Ctrl-C to Stop.

It will throw errors when I try to access localhost:4000 from my web browser and will not serve the files

I am running Windows 8.1 and I have been trying rake preview with both Ruby 1.9.3 and 2.0 and also both x86 and x64 architectures on different machines. Also I tried to disable my firewall but it did not fix the issue.

I'd really appreciate some help to solve this issue.

Thanks.

Solution

After some googling, it looks like this may be a WEBrick specific error with Windows and IE (you didn't list the browser(s) you tried, but most results also list IE as a culprit). I would try:

Hitting http://localhost:4000 from Firefox/Chrome and see if the error persists
Changing your default web server from WEBrick to something else (I'd recommend the Ruby Thin Server). An easy walkthrough specifically for Octopress and the Thin server can be found at this blog post.
