Github's personal page does not refresh with new commits

Question

I have my personal website hosted on github username.imtqy.com repo, it is strange that after I moved my new changes to the repo, the page still showed the contents of my previous commit, but when I checked the contents of this repo on github, this is the last. Any idea what might be wrong. Some say it takes a little time to display new content, but now it has been almost 1 hour.

Answer 1

Finally, there was a problem due to the fact that one module could not be built in my project after it successfully works.
