I don’t think there is error on the code…
I modified program not to use the Sock File and its working well as

[Unit]
Description=Gunicorn instance to serve lolf
After = network.target

[Service]
User=lolfbwu1
Group=www-data
WorkingDirectory=/home/lolfbw/lolf
Environment="PATH=/home/lolfbw/lolf/lolfenv/bin"
ExecStart=/home/lolfbw/lolf/lolfenv/bin/gunicorn --bind 0.0.0.0:5000 wsgi:application

[Install]
WantedBy=multi-user.target

And nginx fie as

server {
    listen 80;
    server_name 10.xxx.xx.xx;

    location / {
       proxy_pass http://10.xxx.xx.xx:5000;
    }
}

Works perfectly file..

Something is not good with Sock File.

Hi there,

Indeed this is a very good finding. I also initially thought that it was due to the Socket file.

I could suggest following the steps here on how to set the permissions for the socket file:

Let me know how it goes!

Bobby
