110: Connection timed out (Nginx/Gunicorn)

I'm running django on gunicorn+nginx. I'm facing a problem with file uploads. Actually uploads are working fine but gunicorn times out thus causing this in nginx:

2011/07/25 12:13:47 [error] 15169#0: *2317 upstream timed out (110: Connection timed out) while reading response header from upstream, client: IP-ADDRESS, server: SERVER, request: "GET /photos/events/event/25 HTTP/1.1", upstream: "http://127.0.0.1:29000/photos/events/event/25", host: "HOST", referrer: "REFERER_ADDRESS"

If I refresh the page, I can see all the photos are uploaded just fine. The problem is that it causes a timeout thus giving the impression that upload did not work.

here is my gunicorn conf:

bind = "127.0.0.1:29000"
logfile = "/path/to/logs/gunicorn.log"
workers = 3

I tried changing timeout but it didn't work.

gunicorn nginx django

You could try upgrading the timeout for your proxy pass in Nginx by adding:

proxy_connect_timeout 75s;
proxy_read_timeout 300s;

on /var/nginx/sites-available/[site-config] or /var/nginx/nginx.conf if you want to increase the timeout limite on all sites served by nginx.

You must add --timeout 300 as well to your gunicorn process/config.

This solved my problems in the past with bigger uploads.

If you are using reverse proxy with Nginx and running the Django app using Gunicorn, try to adjust Gunicorn timeout parameter and proxy_read_timeout parameter from default values.
