When you run your backend you may run to an error similar to the following:

errno: -48,
syscall: 'Listen',
address: '::',
port: 9000

This means that there's another process running at port 9000. You need to either:

  • Change the default port used by the Medusa backend. You can do that by setting the PORT environment variable to a new port. When you do this, make sure to change the port used in other apps that interact with your Medusa backend, such as in your admin or storefront.
  • Terminate other processes running on port 9000.
