ui: CLI - Failed to fetch tree from registry - ERR_SOCKET_CONNECTION_TIMEOUT

I was following the documentation at https://ui.shadcn.com/docs/installation. After initializing the components.json with npx shadcn-ui@latest init I ran npx shadcn-ui@latest add and selected all components. It returns the error: “Failed to fetch tree from registry.” - ERR_SOCKET_CONNECTION_TIMEOUT.

Using the command with a component npx shadcn-ui@latest add avatar does only work for some components, for others like “avatar”, “command”, “toggle” I get the same error.

I tried style: default and style: new-york.

Tried commands:

npx shadcn-ui@latest add (select all components)
npx shadcn-ui@latest add avatar
npx shadcn-ui@latest add avatar --overwrite
npx shadcn-ui@latest add avatar, ...

Error:

you can either a vpn or change your vpn ( in my case windscribe worked ), or you can just install the packages manually, the instructions are on their documents.

My operating environment is Windows. I used Google to look up the IP address for https://www.shadcn-vue.com/registry/styles/index.json and found it to be 104.21.17.226 . and I edited the hosts file on my Windows computer, adding the line:

104.21.17.226 www.shadcn-vue.com

With this addition, the configuration takes effect locally for me; however, some Windows devices might require a restart for the changes in the hosts file to be applied.

Side note: As a Chinese person, dealing with these sorts of network issues can often be quite draining.
