cause
 When I was browsing the blog a few days ago, I found that the comments under my blog could not be loaded. After investigation, it was finally determined that vercel.app was inaccessible due to some mysterious force , resulting in the front-end of Waline unable to connect to the server deployed on vercel .
Solution
 The solution to this problem is very clear: since vercel.app can’t be used, just replace it with another domain name. My solution is to use a second level domain name to assign to the server deployed on Vercel, and then change the server URL in the Hexo config file.
DNS configuration
 Add a CNAME record in the DNS configuration interface of your own domain name, pointing to cname.vercel-dns.com .
Vercel configuration
 The second-level domain name set before adding in Settings-Domains .
Hexo configuration
 Take the Butterfly theme I am currently using as an example, modify it in _config.butterfly.yml
| 1 | waline: | 
It is the second-level domain name set before.
Then regenerate the static page and deploy it.
