error: Someip:port is not a valid port number or address:port pair

Question

This is the first time I am deploying a django application. I created an AWS ec2 ubuntu instance. I followed the steps in this tutorial- https://adeshg7.medium.com/deploy-django-postgresql-on-ec2-using-apache2-from-scratch-42dc8e6682c1 The demo project was running fine on the server http://MyPublicIPv4Address:443. I then added another port in the security groups in AWS, and after that whenever I run "python manage.py runserver http://MyPublicIPv4Address:443 " on the puTTY connection command line, it gives me the same error:

CommandError: "http://MyPublicIPv4Address:443" is not a valid port number or address:port pair.

This seems like a django error in a very old version: https://code.djangoproject.com/ticket/14928. I cant find a way around this error. Any help would be appreciated. Thankyou

Answer 1

while running python manage.py runserver privateIPaddress:port, but in the browser use publicIPaddress:port.
