Bind gtihub pages to your own domain name. Cannot find the server IP address of your domain name

the web page on my github pages was originally accessible through the username .github.io, but after I was bound to my domain name, neither the domain name nor the user name .github.io could be accessed; the IP address
domain name resolution configuration of my domain name server is as follows:

GitHub pagesCNAME
github:

dig,

.
Mar.07,2021

then you can delete the CNAME file first, set a github pages, in setting, and then wait a few minutes to see if you can access it! Troubleshoot the problem step by step? My method is the same as yours, and mine can be accessed.
my configuration is as follows:

Host type host record resolution line
CNAME @ default
A www default
A www default


you can check the domain name on Aliyun or Tencent Cloud platform to check for errors
