I'm trying to run My react-native application, I'm running it on android emulator and my phone HUAWEI Y3II and same thing happens. I was working on it fine a few days ago but suddenly this error keeps coming up:
Could not load exp://*myip*:19000 network response timed out

And the terminal Log shows:

Fetching the user profile failed
connect ETIMEDOUT 104.197.216.164:443
aTrying to open the project on Android...
Opening on Android device

I tried setting the environment variable REACT_NATIVE_PACKAGER_HOSTNAME to my ip address, I tried turning off the firewall, I ensured that the ports are allowed in the firewall, I tried changing my network from public to private. Here is my package.json file:

{
    "main": "node_modules/expo/AppEntry.js",
    "scripts": {
        "start": "expo start",
        "android": "expo start --android",
        "ios": "expo start --ios",
        "web": "expo start --web",
        "eject": "expo eject"
    },
    "dependencies": {
        "expo": "^35.0.0",
        "react": "16.8.3",
        "react-dom": "16.8.3",
        "react-native": "file:../../../../Users/RiggedToBlow/Downloads/Compressed/react-native-sdk-35.0.0.tar.gz",
        "react-native-gesture-handler": "~1.3.0",
        "react-native-reanimated": "~1.2.0",
        "react-native-web": "^0.11.7",
        "react-navigation": "^4.0.10",
        "react-navigation-stack": "^1.9.4"
    },
    "devDependencies": {
        "babel-preset-expo": "^7.0.0"
    },
    "private": true
}

Try clicking the reload icon (the one to the right, not the house). This was all I needed to do. I wouldn't expect that it always works, though. – Maryammaryann 29/9, 2023 at 9:2

Great answer. Thanks. I wasted about 2 hours looking up another post on stackoverflow for the same problem where it said to set an environment variable in command window i.e. set REACT_NATIVE_PACKAGER_HOSTNAME=10.0.0.124 to the wifi IPV4 address obtained from ipconfig command, but it didn't work. This solution you recommended worked. – Walkup 12/8, 2020 at 9:5

make sure that your mobile and computer is connected to the same WIFI network
if your computer is connected to your mobile hotspot then try running the app usingexpo start --tunnel command if it still doesn't solve the issue then
change your WIFI to private and turn off the firewall for private network.

is there any solution that my friend can run an app on his device because we both have different connection at that time?? – Synod 12/12, 2021 at 10:21

Alternatively you need to change your WiFi settings from public to private especially if you have the firewall settings turned on in Windows 10. This worked perfectly for me.

For me, changing the network profile to private was enough. This is good because you should avoid disabling the firewall. – Pomade 14/12, 2021 at 15:14

Make your PC discoverable. Go to the wifi list on the bottom right in windows > click "properties" > toggle the "Network Profile" setting to "Private". Should solve it for you.

simply change your wifi settings to private and turn off the firewall too.

I never had the issue and strangely now, but what you suggested really helped. – Shela 12/9, 2022 at 22:33

Go to your windows firewall settings and set new inbound rule for port 19000.

Expo may give you a QR code that your Android can't reach.

After you check the firewall port 19000, and check that Android is on the same WiFi network as your dev machine, check if the url is 192.168.10.xxx whereas your phone is on 192.168.1.xxx. Find the IP address of your dev machine on the 192.168.1 subnet (same subnet as the Android device). Use that instead.

I fixed this issue in my Ubuntu device by allowing 19000/tcp in my firewall

1- sudo ufw allow 19000/tcp

2- sudo ufw disable

3- sudo ufw enable

4- And then go to your project files and run npm start

That works well with me on Ubuntu,

Thanks.

This solution worked for me. Set your WIFI to private and disable the firewall for a private network.
