I am beginner in python development and I first time tried to upload to server DigitalOcean. I followed this tutorial link. But I have a problem when I finished tutorial 502 Bad Gateway nginx/1.10.0 (Ubuntu)
Zlty.ini
[uwsgi]
module = wsgi:app
master = true
socket = zlty.sock
chmod-socket = 660
vacuum = true
die-on-term = true
Zlty.service

server_name 139.59.145.129;
location / {

uwsgi_pass unix:/home/dendis/zlty/zlty.sock;
}
}
Log in nginx

Replace
with
and restart Nginx. It might help you.

When following this tutorial did you complete the section on creating and testing a sample application. This section included temporarily opening port 5000 and ensuring the app is returned. It sounds like the flask application itself is not responding when it is requested by nginx upstream so working from the bottom of the stack should be the best way to identify the issue.
