After switching from a public IP to an Elastic IP in AWS, my API page is no longer accessible, and Nginx is stuck on the "Welcome to nginx!" page
I initially set up an API on an Ubuntu virtual environment using Nginx, Gunicorn, and Supervisor, and it was working fine with the original public IP address. However, I decided to attach an Elastic IP to the instance. After attaching the Elastic IP, the API page became inaccessible, throwing 404 Not Found.
Steps Taken:
Updated all configurations that referenced the old public IP address to use the new Elastic IP, including:
gunicorn.conf,
settings.py in Django and
Restarted Nginx to apply changes, etc.
Configration: AWS Security groups [Port range, Protocol, Source]: [22, TCP, 0.0.0.0/0], [80, TCP, 0.0.0.0/0], [80, TCP, ::/0]
Questions:
What could be causing Nginx to display the "Welcome to nginx!" page instead of serving my API?
