Github Pages not working

I made a website using React and Nextjs and then exported it using Nextjs’s Static Site Generation Tool… So now, I have a folder with index.html and other components under other folders.

I followed the instruction on this website: https://pages.github.com/ 

and made my repository as here: https://github.com/Jai2500/Jai2500.github.io

But when I went to the link, it shows Site Not Found  

 

It’s not an issue with caching as I tried with multiple browsers and on incognito as well.

Some quick help would be greatly appreciated. 

Thanks,

Jai
