Why is my localhost:8000 loading differently from 127.0.0.1:8000 django website

I'm very confused on my django website right now. I have always used localhost:8000 to check my website and it used to work. Now whenever i make changes to the style.css file, the localhost:8000 wont update the website. Instead, it updates only when i open the website through 127.0.0.1:8000. Anyone know whats the problem here?
