Unity games HTML5

I planned to use unity for HTML5 games, however it seems it is not working on HTML5.
I wrote a simple game in c#. Built and saved as webGL.

I run it under a server however I couldn’t make it run.
Also It seems that on kongregate site unity games, are not working too.

It has worked for me. I don’t know what’s wrong—it should produce a directory containing an .html file, and some other stuff. Opening the .html file in a browser should work.

The other method where you click “build and run” might have trouble for some people because of a firewall. When you say “under a server”, the first thing I think of is “firewall issues”. I did get several games to work by uploading them to itch.io

Ok,
Since i am running unity under Ubuntu i wonder if it is a Unix specific problem.
Unity seems to crash/ has problem under Ubuntu 14 OS.
I will try again under W7 and see how it goes.

My main concern is would HTML5 publisher would accept unity games for their HTML5 platforms.
Since this seems to be the only option for Low budget studio to get some income…
