# Npm start script opens http://localhost:3000/#/login route instead of http://localhost:8080 . Is it something I should fix on my machine?

I’ve started following the Setup guide for the course **MoT Foundation Certificate in Test Automation - Javascript** placed on this page: [Sign In | Ministry of Testing](https://www.ministryoftesting.com/certification-paths/mot-foundation-certificate-in-test-automation-javascript) under **Setting up the support application** section

Everything works as expected, but when I ran `npm start` command, it launched an app on another port than it was described in the setup guide (localhost:3000 instead of localhost:8080). When I tried to navigate to localhost:8080, it returned a 403 error.

Is it something I should fix on my machine?

If it’s working on port 3000, there is no need to change it. Simply use this port in your browser and tests.

The setup guide may need updating.
