This port number 49342 is like a special bridge that applications use to connect to each other on your device.

In other words, you don’t need to worry about different applications using different ports on the same local IP.

If you are testing web apps or locally running servers, figuring out how this two go together can make the development and debugging process so much easier!

The Basics of “127.0.0.1:49342”

“127.0.0.1:49342” is an address that looks very strange at first, but is quite important in local web development.

Or, perhaps firewall blocks the port specified. If you have a firewall check it to ensure it’s not blocking connections.

Check the URL again for any typos or bad parameters if you are using a browser and receive an error message.

Applications will not load after restarting usually fixes short-lived problems related to network services or code changes.

If there are conflicting apps that are using the same port but another app is trying to do it on the same port change the listening port of one app for a time so that things don’t get interrupted.
