Check if you have any other Node.js servers or applications running on Glitch that are using port 3000.
You can change the port number your Node.js server listens on. may be if help you see the Ref:

Error: listen EADDRINUSE: address already in use :::3000 (fixes from similar topics did not resolve)

Thank you for responding! Those commands were not working for some reason. I actually ended up asking “ChatGPT” for a bit, and it revealed that to find the process that needs to be “killed” in the Glitch terminal, you must first run: netstat -lnp | grep :3000 Then I would run: kill <# of the process needing killed> or kill -9 <# of the process needing killed> and then run: refresh then: npm start I also had to change my PORT to NOT include 3000, since this is the default Glitch will run…
