My GitHub page isn't publish

I used GitHub to host one of my webpage https://khanhmai20.github.io/biography/Source/biography.html

At first, I can open this webpage and view all the content. After I committed changes to this webpage (through my local terminal). Github page didn’t host my website any more and printed out an 404 errors

@khanhmai20,

Generally the “GitHub Actions” zone is used to discussion the GitHub Actions workflows . If you have any questions or problems about workflow configuration, such as syntax, GitHub-hosted runners, or building actions, you can post tickets here for support, and we will provide the help as much as we can.

About the question of GitHub Pages, you can post your tickets in the “GitHub Pages” zone for more detailed and in-depth support.

In addition, you can view more information about GitHub Pages from the official documentation below:

Thanks for your understanding.
