I'm getting an error when running my Django app with gunicorn: when I make a post request over 7800 bytes I see the following error from gunicorn:

"Error opening file for reading: Permission denied".

It then drops the request and nginx is getting a "Connection reset by peer" error.

This doesn't happen if I run the Django development server instead. Strangely, if I make the request to an invalid URL, no matter what the post content length, I get the standard Django debug webpage.

So it seems to be how gunicorn is handling something that Django is doing when it's processing a request for a valid view URL.

This is being run on Ubuntu 12.04. I've tried running Gunicorn as root and it still happens.

I'm at a bit of a loss on how to debug this any further. I've tried setting the tmp_upload_dir to a directory will full permissions incase that was an issue, but no luck.

Any advice would really be appreciated.

You need to allow the host in the ALLOWED_HOSTS in your


I would expect a more descriptive error message, but unfortunately, this is what we get.

I don't think it's this because I'm running with DEBUG=True – Michael Waterfall Sep 9 '13 at 21:46
It's not a production server, just another development machine running gunicorn. – Michael Waterfall Sep 9 '13 at 21:47
yeah this didn't fix it for me either, I had the proper allowed hosts in there already. What did it was running chown -R my_id:my_gid * on my entire django project. It should be the same user/group used to run gunicorn i.e. --user --group in your conf file, or by default its the user you are logged in as. – radtek Aug 6 '14 at 20:03
