Connection refused with uwsgi and nginx

followed one of the tutorials on digitalocean to be able to set up a flask app using uwsgi and nginx.

But I am having a 502 Bad Gateway error everytime I try to connect to it. When looking in the /var/log/nginx/errors.log it shows that the connection was refused.

I have been trying to figure this out for days. Can someone please tell me whats wrong? I think it’s the permissions but I dont know what the permissions are suppose to be.

/var/log/nginx/error.log:

2016/08/01 16:12:13 [error] 18539#18539: *1 connect() to unix:/home/lit/howlit/how_lit_restapi.sock failed (111: Connection refused) while connecting to upstream,

here is my howlit.ini file:

[uwsgi]
module = wsgi:app


master = true
processes = 5


socket = how_lit_restapi.sock

chmod-sock = 666

vaccum = true

die-on-term = true

Here is my permissions in the app directory:

drwx---r-x 6 lit www-data 4096 Jul 29 11:47 env
-rwx---r-x 1 lit www-data  141 Jul 29 19:01 howlit.ini
