Assuming you're using nginx to proxy? Make sure it is up to date (> 1.3.13)

You are correct. I am using ubuntu 12.04 and the version of nginx is low. After I upgrade nginx, it works. Thank you.

I confirm the upgrade of the nginx increase the performance of nodebb. (index page was often realy slow / and some times crashes) The latest stable version of nxing has resolved this problems.

To upgrade on ubuntu:

    sudo apt-get install software-properties-common
    sudo add-apt-repository ppa:nginx/stable
    sudo apt-get update
    sudo apt-get install nginx
