utterances redirect 404

I got it on my personal website. Add code: ```<script src="https://utteranc.es/client.js" repo="zhaobokai341/zhaobokai341.github.io" issue-term="url" theme="github-light" crossorigin="anonymous" async> </script>```,result:  It can be authorized, but 404 after authorization:  gongju.html is a file that I used to delete.zhaobokai341.github.io is my Github Pages. Thanks.
