(main_jntu) is my project name

at that also i have got server error (500)

please help me this out. and thanks

Looks like something else is already using port 80. On a linux box, it's typically either nginx or apache. You should turn off that web server first before starting a new one. — Håken Lid, Feb 12 '20 at 19:01

@HåkenLid the error which i have before also when iam not using nginx and iam just using. gunicorn --bind 0.0.0.0:8000 main_jntu.wsgi:application at that time also i have got the server error — Rajashekhar Reddy, Feb 12 '20 at 19:05
I'm confused. You have gunicorn opening port 8000 but then the nginx config seems to be pointing to a unix socket. — Tim Tisdall, Feb 12 '20 at 19:58
