You most likely don't have a problem with your nginx server. Your nginx server has a problem reading a response from your Django application which is the reason it times out. It can be a bit tricky to figure out the cause of the heavy load, but I would start by looking in your Django server logs and see if there might be something obvious there. If you have a chance to get a look at your server while it's under heavy load and starts giving timeouts, something like htop and similar tools might be able to give you a hint at the bottleneck. If you're database server is maxing out all your CPU cores, then that could give a good hint on where to look. Hope that helps a bit.
