How do I fix error 1078#0? Bad Gateway nginx/1.4.6 (Ubuntu)?

Hello guys and girls,

I am getting an error 1078#0 while trying to get my website up and going. Let me give you a chronology of events plus an error log:

I first brought Putty up and went to access my server. I got the Django "It Worked!" message.

After that I went to upgrade my Django and it updated to 1.11. i ran, in the Putty command, "service gunicorn restart".

Got 502 Bad Gateway

I unistalled Django and was back to version 1.6.1. Refreshed. "Internal Server Error"

So i "pip install django==1.9" and checked version to ensure i was running Django 1.9. "service gunicorn restart". Restarted. Refreshed. 502 Bad Gateway Error nginx/1.4.6 (Ubuntu).

Here are the errors I am getting when I run "tail -f /var/log/nginx/error.log": [error] 1078#0: *263 connect() failed (111: Connection refused) while connecting to upstream, client: XX.XXX.XXX.XX, server: _, request: "GET / HTTP/1.1", upstream: "", host: "XXX.XXX.X.XX"

Can someone please tell me what is going on here and why? It is very frustrating and getting this website up is mission critical as I have just filed my company and am ready to begin operation.

Hi @dayscue

We need the error log from Gunicorn, since that's the service not running - Nginx only return the default 502 Bad Gateway, since it cannot connect to anything.
It's normally located in /var/log/upstart/gunicorn.log but you might run it with a different job name and then you have to look for /var/log/upstart/$JOB_NAME.log.

EDIT: But if you don't see any logs, then you might need to update your Gunicorn script to include the --error-logfile /path/to/log/file:

But since you haven't used the server yet, then you could just rebuild it (you will lose all data on the server) back to the Django One-Click.
If you want to rebuild, go to the DigitalOcean control panel, click the droplet, click the Destroy menu on the left, search for "Django", select the image and click Rebuild.

  • Okay so how do I do what you just told me? K-12 it for me if you can. where would /var/log/upstart/gunicorn be located? and then you say i might need to update gunicorn script. how do i go about this all?

      tail -30 /var/log/upstart/gunicorn.log

      If you don't know how to get around in Linux, then I would probably recommend that you just rebuild the server with a One-Click App (which is almost the same as deleting it and creating a new).
