Urls.py not updating on Django production server , which uses nginx and gunicorn

I am currently hosting a Django Webapp , To run it in production mode I use NGINX and gunicorn.

The Error that I am facing is:

The production server doesnt seem to update urls.py, no matter what I do

App used to transfer files from local file to instance : FileZilla

Steps that I have taken trying to solve the issue:

1.Deleting the urls.py and rewriting it

2.Checking if other files also refuse to get updated

RESULT of 2nd step: Other files are successfully getting updated, I tested with static files and with index.html

3.Checking if the file is updated in the instance using The nano editor

RESULT of 3rd step: The file is properly updated in the instance, with all changes being reflected

4.Running it on the instance using python manage.py runserver (for development purposes), and found out that the urls.py is getting updated properly when using runserver

Other Information:

1.Everything was getting updated properly just yesterday, but suddenly it decides to act rebellious

2.I have updated all packages using sudo yum install

3.I have restarted nginx and gunicorn: using commands such as :

sudo systemctl enable gunicorn

sudo systemctl restart nginx```

4.I have tried checking for errors using ```sudo nginx -t```, but no errors show up

5.I've checked the error logs, using ```sudo tail -f /var/log/nginx/error.log``` , but no errors show
up here either

How do I solve this?

Thank you
