React-native Timeout when connecting to remote debugger in windows

Question

I am new to React-Native and android app development as a whole. While i try to run remote debugger in Android Emulator (Pixel 2 phone), I get the following error in the emulator:

Then after, even if I stop remote debugging, the application won't run on the emulator (i.e. nothing is rendered into the emulator screen). I need to run the project again.

Following is the auto-generated debugger URL: http://10.0.2.2:8081/debugger-ui

How can I Fix this problem?

Solution 1

http://10.0.2.2:8081/debugger-ui This is internal IP the Android VM, with your browser use localhost:8081/debugger-ui reference https://github.com/facebook/react-native/issues/16674#issuecomment-376774645

Solution 2

uninstall your application, then run => react-native run-android in terminal then click debugging end in chrome replace http://localhost:8081/debugger-ui/, end run react-native run-android. if you still haven't succeeded try again

Whenever i manually insert the URL: localhost:8081/debugger-ui and then re-run the application using react-native run-android , and then start debugger it works. Otherwise in case of the auto-generated debugger URL: 10.0.2.2:8081/debugger-ui, it deos not work!! I tried changing default debug server URL, but then it throws some new error along the way.. what can i do here?

Please use localhost:8081/debugger-ui instead of 10.0.2.2:8081/debugger-ui the React Native version is 0.55.4.
