This is not an issue related to the actual beego go module, but rather its related documentation site beego.me

The website located at beego.me is no longer accessible with an error message from UCloud. Screenshot attached as below.

Some suggestions for alternatives if you don't want to do ICP Beian for the website: CloudFlare Pages, GitHub Pages, and Netlify. All of those come with nice dashboard UIs along with CI/CD features.
