Error: You don't have permission to access that port

I have django application running on ubuntu 18.04 LTS. All of a sudden I started getting below error while running server.

$ python manage.py runserver localhost:9000
Performing system checks...

Quit the server with CONTROL-C.
**Error: You don't have permission to access that port.**

Before this error, I updated to ubuntu.base through livepatch. Please suggest how can I resolve this error or uninstall the latest livepatch. Thanks in advance.

You can use another port for your django development server port to running.

for example

python manage.py runserver localhost:18080

This issue was in a particular git branch only. I am still not sure what is wrong with it. As of now, I created new branch and it is working fine.
