GitHub page appears at 404 error

GitHub page appears at 404 error.

I’ve been pushing since last night, and it hasn’t been reflected.
The page doesn’t show up like this.

$jekyll serve

Am I the only one like this?
Is there anyone who has the same issue as me?

Am I doing something wrong?
Please help me!:exploding_head::exploding_head::exploding_head::exploding_head:

Hi @minheeyoon, welcome to the GitHub Support Community! It looks like that site is working now. I notice that your last commit to that repository was 7 hours ago. Did you manage to figure out a solution?

Nice to meet you. @thomasshaped Thank you for your reply.
Eventually, i solved this problem by rebuilding the repository :joy: :joy:
