EADDRINUSE error

[alexsmith1665]

Hello, I am getting the following error when I try to run "node index.js"

/home/pi/MagicMirror/node_modules/node-fauxmo/src/SSDPService.js:104
throw err;
^

Error: bind EADDRINUSE 0.0.0.0:1900

I see in your instructions that I need to find what device is listening on port 1900, but I'm not sure how to do that. Could you tell me how to figure that out? I have successfully run the command before with no issues. I have not added any new devices since then.

edit: I pasted the wrong error message, so I updated it to the correct one.

Is this module still maintained?
