By default, my application is using port 8080, but i want it to use port 3000 instead That doesn’t even have an eight in it anywhere I tried adding a new variable called port:3000 in the configuration>application settings.

Quickly find out what’s blocking your port and safely shut it down — no reboot needed.
While 8080 is prevalent for many node.js applications, ports like 3000 and 3001 are also perfectly valid options
Always remember, it's essential to ensure your chosen ports do not conflict. Ever wondered why your dev servers always run on localhost:3000 or localhost:5173 These ports have fascinating histories that trace back through decades of developer habits, from java and python to node.js and vite. Choosing the right port often depends on your specific needs and any potential conflicts with other applications
These alternatives offer flexibility and options for different development scenarios. Additionally, if another program is already using the same port, your app will throw a “port already in. People generally pick something fairly unused but also easy to remember, then things stick and get used by convention, so 3000 and 8080 are common ports for development servers. Port 8080 was used by unreal tournament and microsoft lync — but also by trojans and backdoor worm exploits
Port 8888 was used by mamp — but also, you get it, more malware
So what about port 3000
