Github Page not working

Hello, I changed the name of my github page about a month ago and now it’s not working:

adamgoldstein.github.io

Hi @adam-goldstein, welcome to the GitHub Support Community! It looks like that repository has been renamed to match your GitHub username so it should now be online at https://adam-goldstein.github.io/ :tada:
