React-Native Error: Connection to http://localhost:8081/debugger-proxy?role=client timed out

Solution 1:

For remote debugging, Your both devices must be connected to the same wifi ( network ).

Solution 2:

I get this issue often. Usually when I'm developing with the remote debugger on and I save codebreaking kind of error.

Try to reload... If that doesn't fix it: crlt + cmd + z. then stop remote debugging, then refresh. That will fix it but now you lost your debugger. So go again... crlt + cmd + z. this time start remote debugging, then refresh again. Your project should be back and good to go.

This works for me, but it's super annoying and time-consuming. I wish someone had a better way.

Solution 3:

I somehow managed to make it work without creating a new project by deleting the project app in the simulator on the iOS home screen. It works fine now.
