I got mine running fine except i can't view any site.. only getting "This webpage is not available".

Make sure you append :8000 to the end of your domain and have added it to the hosts

127.0.0.1         homestead.app

I should also specify, my trouble connecting is during vagrant up. It boots the VM, tries to connect, fails, then destroys and I'm back to square one. That's where the error I mentioned in the initial post shows up.

Your Homestead.yaml "sites: to:" probably point to wrong or not existing directory. Also, check /etc/nginx/sites-available/homestead.app

Thank you, ratiw! Very helpful information which solved my problem and helped prevent some others.
