Fix React-Django API Connection

My website is having issues connecting React to a Django REST framework API. Although the API itself is functioning correctly, I am encountering a "Network Error" when using axios from React. I would like you to troubleshoot this issue and also write a test in React to verify the connection.

Skills and Experience:
- Proficient in React (version 18) and Django
- Experience with REST APIs and Axios
- Knowledgeable in configuring CORS
- Capable of writing tests in React
