I am currently trying to host a Django application on Railway, but I am facing an issue in the Gunicorn server which keeps getting stuck at [DEBUG] Closing Connection. status, below are my logs.
gunicorn.conf.py
# Non logging stuff
bind = "0.0.0.0:8000"
workers = 3
# Access log - records incoming HTTP requests
accesslog = "-"
# Error log - records Gunicorn server goings-on
errorlog = "-"
# Whether to send Django output to the error log
capture_output = True
# How verbose the Gunicorn error logs should be
loglevel = "debug"
# Increase the timeout for each worker to 90 seconds
timeout = 90

The odd part is that sometimes the webapp works fine and then suddenly crashes in the production, I have already tried running the gunicorn sever locally with the remote database, it works fine locally.
Here I have purposefully downgraded the gunicorn and Django versions since a issue said the [DEBUG] Closing Connection. is caused in gunicorn 20 and Django 4.2 due to internal dependency conflicts. Issue Reference
I have tried to change the server from gunicorn to waitress or even the bare python manage.py runserver, but none of the solutions have worked so far.
