Django Admin Panel and Sub URLs Returning 404 Error on Deployment

Question

have recently deployed my Django project to a server, and while the index URL (mannyebi.com) loads correctly along with static files, accessing sub URLs such as mannyebi.com/blogs or even the admin panel (mannyebi.com/admin) results in a 404 error.

Locally, the project runs smoothly, indicating the issue may stem from the deployment configuration. I've ensured that all necessary URL patterns are defined in the urls.py files and that Django's admin app is properly installed and configured.

However, despite these measures, I'm still encountering difficulties accessing sub URLs beyond the homepage. Is there a specific configuration step or server setting that I might be overlooking to resolve this 404 error and enable access to sub URLs on my deployment? Any insights or troubleshooting suggestions would be greatly appreciated.

I deployed my Django project to a server. Upon navigating to sub URLs such as mannyebi.com/blogs or mannyebi.com/admin, I encountered a 404 error.

I verified that all necessary URL patterns were defined in urls.py and that Django's admin app was properly configured. I expected these URLs to load correctly, similar to how they did on my local development environment. However, despite these efforts, the 404 errors persisted.

I'm seeking guidance on resolving this issue and enabling access to sub URLs on the deployment.
