Workspace preview port selection

Hi guys,

Im having difficulty when I want to view my work on workspace in preview mode. It keeps asking me about which port I want to use to preview my work. So, basically, which port I should choose to preview my work in workspace? I've tried them all, but no one worked for me. Any answer will be highly respected.

Thanks guys!

If none of the ports seem to work, then it can be due to one of the following reasons:

  1. The web server (that serves your application to clients such as browsers) may not be running. This can be due to an error in your application that caused the web server to crash.
  2. The web server may be running, but listening on a different port than the ones listed under "Preview Workspace" option.
  3. The web server may be running, but request URL path (such as '/') may not have been configured to return a response.
