Second github website not working

Hi,
I have hosted my first github webiste using the repo name “.github.io” with source branch called “main” and it works just fine.
My second repo name is “portfolio” and the source branch is called “boss”. I linked the branch to github pages and it hosts it at “.github.io/portfolio/”. The first html page is displayed and none of the others. the repo link is https://github.com/codedmachine111/portfolio . Can someone please check it out and help me?
Thanks.

it’s working, what is the problem? you think that at the URL, it should be boss instead of portfolio?

if you want that, change the repo name to boss, if you don’t have any other repo with the same name,

then you should access that using boss not portfolio

And the other pages are also working, so I think, you already solved this, right?
