Ali Cloud self-test list:

  1. has the whitelist of the security group been added?
  2. can ssh be connected? Is the machine monitoring normal?
  3. Is the
  4. service open? Is there any error in the environment log?
  5. what is the HTTP return code / service error code?

  1. console.log ( Server running at http://${hostname}:${port}/);) is printed yet?

2. If you follow the tutorial, is it open in the port 3000 security group?
