Can not publish the package to npm instance level registry but project level works

I want to use instance level NPM registry on the self-managed gitlab. But I can not publish the package to gitlab group with the error 404.
I have checked the doc and config the .npmrc, look like blew:


ant it shows:

npm ERR! code E404
npm ERR! 404 Not Found - PUT - 404 Not Found
npm ERR! 404 
npm ERR! 404  '@lemon-fe/components@0.0.1' is not in the npm registry.
npm ERR! 404 You should bug the author to publish it (or use the name yourself!)

lemon-fe is my group name
Then I tried the project level registry and it works. but I still want to use the instance level registry

Any ideas?
Thanks a lot
