Problem: After an Ubuntu 22.04 upgrade, LTS ??? I got the 503 error, nginx was up but gunicorn show failed and all the settings were still good/unchanged.

Solution: Reinstall my local packages; PIP was gone and my other Application packages too; Django,…and gunicorn specifically cause that was the error I was chasing down.

Check your packages.

Hi there,

I could suggest following the steps from step 11 in this tutorial here:

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04#step-11-troubleshooting-nginx-and-gunicorn

This includes some commands that would help you find more information on why the Gunicorn service is not running.

Feel free to share the output of the logs here so we could try to advise you further.

Best,

Bobby
