400 error, nginx debug log confusion, Django app

[Tom Tanner]

Note: `mydomain.com` is not my real domain name.

When I go to `test.mydomain.com`, I get a page that just says `Bad Request (400)`. 

I'm running a Django app located at `/home/django/product_blog`.

Here are the contents of my nginx file at `/etc/nginx/sites-available/BRBR2`.

    server {

        listen 80;

        server_name test.mydomain.com;

        error_log /var/log/nginx/debug.log debug;

    

        location = /favicon.ico { access_log off; log_not_found off; }

        location /static/ {

            root /home/django/product_blog;

        }

    

        location / {

            include         uwsgi_params;

            uwsgi_pass      unix:/home/django/product_blog/product_blog.sock;

        }

    }

When I go to the debug file after trying to load the site, I see this: https://pastebin.com/GchPd1MD.

The file at `/var/log/nginx/error.log` shows nothing.

How do I find the source of the 400 error?

I ran `sudo reboot` and `sudo service nginx configtest && sudo service nginx restart`. Now the site loads just fine. I don't know which of those two commands did it.
