My problem is simply when I go to username.github.io it takes me to another page in my repo rather than index.html however, when I go to https://username.github.io/index.html it works correctly. I would rather have username.github.io point directly to index.html.
Note: My problem is NOT like the problem here My problem is also NOT like the problem here as "waiting" doesn't fix it, nor do any of the other solutions given
Edit: It is consistent, rather than going to index.html it takes me to a page where I'm hosting a game I made, which also is in a whole other directory and is not even titled index.html.
