github pages not detecting index.html

I created a repo github page https://khoihuynh.github.io/ and i've push my code in there, but it doesnt seem to be detecting my index.html file. It's just giving me the default page:

I've tried https://khoihuynh.github.io/index.html but no luck. I've also tried creating a new repo. And i've tried clearing my cache also, no luck. Running my index.html locally works on my browser

My code repo is here: https://github.com/KhoiHuynh/khoihuynh.github.io
