can you post the exact text of the error message or a screenshot next time this happens?

sdHi cchever error have two kind like this:

hi ccheever … bellow are the two error, can you tell me how to solve this

What is the output from the packager? Are you using create-react-native-app or XDE?

I am using XDE, the output is tell about 404 something like that if I m not forgot.

Can you try restarting XDE? Or putting a link to your code on Github here? It’s hard to tell what’s going on from what you’ve told me.

Hi ccheever:

In browser console log error like this : WebSocket connection to ‘ws://localhost:19001/debugger-proxy?role=debugger&name=Chrome’ failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED.

And in from the output of expo like below:
