Body

I created a blog and it can be accessed normally on gitpages. However, when accessing the website under a personally defined domain name, some requests are 404. I don’t know why this happens?
My warehouse address is: https://github.com/dreamshao/xingblog.github.io, and the blog URL is: https://8888666.top/, I hope it can help me solve the problem that has been bothering me for a long time.
