NPM registry token not found

I'm trying to setup a travis build for my npm package.

Before commiting & trying this, I'm checking that the NPM provided is correct.

To get my token I just use NPM CLI and use npm login connect with my account in my current pc.

But when I test the token using this link :

http://registry.npmjs.org/:_authToken={MY_AUTH_TOKEN}

The website return this error :

{"code":"ResourceNotFound","message":"/:_authToken={MY_AUTH_TOKEN} does not exist"}

Anybody knows if the registry need some time to get the new token or if i'm doing something wrong?
