Node.js Port 3000 already in use but it actually isn't?

Question

I have been working with a node.js project for a few weeks and it has been working great. Usually, I use npm start to run my app and view it in a browser on loc

Answer 1

In package.json scripts inlcude:

"start": "nodemon app.js --delay 1500ms"

I believe the issue was for me the time that the old port was not shutting down in time by nodemon for the restart. I experienced the issue using multer.
