"connect ETIMEDOUT" error when I tried to debug the react-native app

I have something to tell you.
When I tried to debug the react-native app,
I get an error of "connect ETIMEDOUT 10.0.2.16:8083".
If the Android API level is 30 or less, you can debug without problems,
An error occurs if the Android API level is 31 or higher.
I haven't made any special network settings.
What is the cause?
react-native: 0.60.6
debug tool: VSCode

After building the app
When I run it on my virtual device it doesn't even open it keeps stopping
I checked the logcat

Double check your gradle file for correct import of ad services and upgrade all dependencies to the latest versions. Check out Set Up Google Play Services for more details. I say this because your error code states:
Caused by: java.lang.IllegalStateException:
at com.google.android.gms.internal.ads.zzze.attachInfo(Unknown Source:17)
at com.google.android.gms.ads.MobileAdsInitProvider.attachInfo(Unknown Source:3)
This seems to suggest that gms.ads is attempting to attach and the source is unknown. Please post your gradle files or more of the error code if updating the dependencies doesn't work.

Add your AppId in your manifest file like this
<manifest>
<application>
<!-- TODO: Replace with your real AdMob app ID -->
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="ca-app-pub-################~##########"/>
</application>

How can I open my node.js program in chrome? - VS Code

I'm new to node.js, and VS Code. I'm watching this tutorial, and the issue is that in the video, he runs his server. I can do this fine, but, when he opens his browser and types http://localhost:8888, he can connect to the server like he is a client. When I do this, the program Emit(I think that is what its called) opens and has an error - Error: ENOENT: no such file or directory, open 'h:\Microsoft VS Code\bin\index.html' at Error (native). In the beginning of the tutorial, he went to edit configurations and entered the local host url into some text box and changed other settings. Although, he is using IntelliJ, and I'm using VS Code. How can I make it so I can enter the url and run as a client.
[EDIT]: When I try to start without debugging, I get the options select enviornment - Chrome or Node.js. Also, I went to the terminal and typed node app(file name is App.js), and I get the error in the terminal - module.js: 471. throw err. Error: cannot find module at C:Users\Name\App
Thank you.

Unable to launch Appcelerator IDE?

Followed Steps provided by platform.appcelerator.com :
Account Created
Download Appcelerator Studio IDE
Installed Sucessfully
Launching by providing Username and Password
Error Occurred and unable to lanunch , Here is screenshot:
Kindly help to solve this issue . Any help is highy appreciated.

The problem is - Appcelerator Studio is unable to install latest appc CLI due to proxy/network configuration issues.
To identify the root cause.
Open a terminal and run the below command.
appc use latest
Is it the same error which you've reported? If yes, verify proxy configuration
appc config get proxyServer
Does it show any configured proxy? If yes, and it was set unintentionally, you can remove that by running the below command.
appc config set proxyServer
This will nullify your proxy configuration.
If there is no proxy configured, still you are facing the issue. Then, your network firewall is not allowing to access Appcelerator Software Update site.
Contact your network admin to unblock it.

Eclipse with Webclipse - JS debugger doesn't stop at breakpoints

I'm using Eclipse 4.5 and I've installed Webclipse 2015 CI 8 and Tomcat 8.0. I'm trying to debug an example. But the debugger doesn't stop at a breakpoint. It runs through the whole file and shows
Uncaught TypeError: $(...)[methodToCall] is not a function
at doExceptions (http://localhost:8080/Webclipse-JSDebug-WebApp-Example/:180:42)
at (http://localhost:8080/Webclipse-JSDebug-WebApp-Example/:181:6)
Failed to load resource: the server responded with a status of 404 (Not Found)
Uncaught TypeError: $(...)[methodToCall] is not a function
at doExceptions (http://localhost:8080/Webclipse-JSDebug-WebApp-Example/:180:42)
at (http://localhost:8080/Webclipse-JSDebug-WebApp-Example/:181:6)
What did I do wrong?
I've installed Webclipse 2016 and I've got the same problem. Anybody knows why?

I'm not positive about the exceptions, however, a possible reason for skipping the breakpoints would be if you right clicked the project and chose debug as -> debug on server. Instead, select debug as -> JavaScript in JavaEE Web Application. This should start the server and open the application in chrome, pausing at the breakpoints.
