Fork repository from github pages?

Question

git

I'm forking a repository from github pages, but github pages don't work on my fork.
What to do and how to treat?
Why are the pages not working automatically?
For example, let's take a toy 2048 . At the address of the original gabrielecirulli.github.io/2048 everything opens fine, but on my fork there is a 404 error .

Answer 1

Everything opens up. :)
Heading 22048. :o
