Unable to listen on http://127.0.0.1:1880/

Whenever I try starting up Node-RED in Linux it comes up with this:

What can I do to fix this? I've been through every forum that has a similar error, and nothing works or is relatable to my problem. Any help would be greatly appreciated. Thank you for your time!

Have a look with sudo netstat -ltup what program uses port 1880.
After that you can decide if the other program or nr can be set to a different port.

That almost certainly means you already have node-red running. Perhaps you have enabled it to run on boot. You haven't said how you have installed it, but perhaps
sudo systemctl status nodered
will give a clue.
