Getting ERR_CONNECTION_RESET while playing mp3 audio

I am using the following code:

var sound = new Audio(path);
sound.load();

Then I'm playing it. It starts playing about 10-15 seconds. But then it stops. The console on chrome shows an error:

localhost:8080/sounds/music.mp3 net::ERR_CONNECTION_RESET

What is the problem here? When opening file directly from browser, it loads and plays normally.
