GitHub Pages Custom Domain Binding Failure

Temporarily hosted my blog on GitHub Pages and pointed my personal domain to the blog. However, every time I configured the Custom domain and accessed it successfully, it would eventually return a 404 error without notice. After some investigation, I found that the Custom domain setting was being reset and becoming invalid after each hexo deploy.

• Add a CNAME file in the source folder of the project, and fill in your domain address in the file. Note that this should be the source folder where resources are stored, not the source folder under the theme. Additionally, the CNAME file has no file extension.
• After redeploying, there is no need to manually modify the configuration again. ogImage: https://image.coldcoding.top/file/AgACAgQAAyEGAASUgNIDAAOdZ-LLW2SY1yk2VuSGbtbqq3iEFT4AAgPGMRuknBlTlzRoYu-UvNoBAAMCAAN3AAM2BA.jpg
