Nginx – uWSGI is ignoring uid, gid and chown-socket

I'm trying to use uWSGI with nginx. The root problem I am having is that I'm getting "No such file or directory" from nginx trying to connect to the uWSGI socket file.

When I use the following settings, I am expecting the socket file's permissions to change. However, they aren't. It continues to show uwsgi:uwsgi.

The error from nginx is *17 connect() to unix:/tmp/myapp.sock failed (2: No such file or directory) while connecting to upstream, client: 192.168.1.122, server: , request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/tmp/myapp.sock:", host: "192.168.1.123:81"

myapp.ini (uwsgi)

[uwsgi]
chdir = /var/local/myapp
plugins = python
module = wsgi:app
home = /var/local/virtualenv/myapp
file = main.py
daemonize = /var/log/uwsgi/myapp.log
pidfile = /var/run/uwsgi/myapp.pid
socket = /tmp/%n.sock

chmod-socket = 777
chown-socket = webuser:nginx
uid = webuser
gid = nginx

vacuum = true

file permissions

srwxrwxrwx.  1 uwsgi uwsgi    0 Jul  3 12:43 myapp.sock

myapp.conf (nginx)

server {
    listen 81;

    access_log /var/log/nginx/myapp_access.log;
    error_log /var/log/nginx/myapp_error.log;

    location / {
        try_files $uri @yourapplication;
    }

    location @yourapplication {
        include uwsgi_params;
        uwsgi_pass unix:/tmp/myapp.sock;
    }
}

I also tried this:

usermod -a -G nginx uwsgi
usermod -a -G uwsgi nginx
useradd webuser
usermod -a -G nginx webuser
usermod -a -G uwsgi webuser

and I tried this:

grep avc /var/log/audit/audit.log | audit2allow -M nginx
semodule -i nginx.pp

EDIT

and I tried moving the sock file to /var/run/uwsgi/myapp.sock. In that case, nginx tells me: connect() to unix:/var/run/uwsgi/myapp.sock failed (13: Permission denied) while connecting to upstream

EDIT 2

and just for kix, I tried to use TCP port instead of a socket file. In that situation, I can use curl -XGET http://localhost:8000 and get the proper HTTP response from uwsgi/python. However, in the nginx log (when attempted to come in via the browser through nginx, I get: *1 connect() failed (111: Connection refused) while connecting to upstream The nginx file is configured like this: uwsgi_pass uwsgi://localhost:8000;
