Answer 1

Thanks to everyone on stack overflow I solved my solution by myself. For others who find this error.

1. your connection should be the same on your phone and on your PC.
2. Internet connection your PC is connected to should have the firewall disabled.
3. If still a problem you see something like exp:127..... You can change your lan address and you can see it using expo start --lan. And use this command to change your URL set REACT_NATIVE_PACKAGER_HOSTNAME=192.168.0.100 <- your ip address

powershell: $Env:REACT_NATIVE_PACKAGER_HOSTNAME="192.168.0.100" – Smithson

Answer 2

If you run :

npx expo start --tunnel

and doesn't work then first run this command in your command prompt:

npm install --global @expo/ngrok@^4.1.0

before starting your app again with:

npx expo start --tunnel

In my case nothing worked.. But When I try this https://docs.expo.dev/get-started/create-a-project/#open-the-app-on-your-device

npx expo start --tunnel

It worked. Hope it helps.

Answer 4

In my case, I recently installed an antivirus which setup firewall.

1. Uninstall the antivirus
2. Restart my system
3. Restart the server

It works fine after that.
