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
