Another process already listening at this address

Hello all!

Running into this issue when you type node-debug src/app.js?

Cannot start the server at 127.0.0.1:8080. Error: listen EADDRINUSE 127.0.0.1:8080.
There is another process already listening at this address.

Here is what worked for me instead:

node-debug -p 5859 src/app.js

Hope this helps!

You might want to identify which process is currently using that port, and if it's not something you intended to keep running, you may want to stop it.

One possibility is It could be an old instance of node still running in the background.
