Internal Server Error when i try to access my ip

Question

I am new to cloud hosting but i have been able to launch my django project which works well however i woke to the surprise that my ip address no longer works, it just shows 404 Not Found nginx/1.14.0 (Ubuntu) and the domain linked to the ip now shows internal server error. I have checked my droplet and it seems just fine; i have no clue why this happened. Any help will be appreciated. Thanks

Hello,

I would recommend starting with your Nginx error log first. This would give you more information about what could be wrong. You could check the last 100 lines in your error log with the following command:

tail -100 /var/log/nginx/error.log

If you are unsure, you could share the errors here and I could try to advise you further.

Hope that this helps!
Regards,
Bobby

Hi @dronerscomng

It looks like that the gunicorn socket is not available and Nginx is failing to connect to it. It might be a configuration problem.

I would recommend following the steps here on how to create a systemd Socket and Service Files for Gunicorn:

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04#creating-systemd-socket-and-service-files-for-gunicorn

Let me know how it goes.

Regards,
Bobby

I fixed the 404 page but now i get 502 Bad Gateway, i think it has to do with Active: failed (Result: service-start-limit-hit)
