When the QR code on the dashboard of my laptop is scanned by the Scanner of Expo in my Android, it shows the error "Something went wrong Network response time out".

And when I open error log file, it shows "Uncaught Error: Java. net. SocketTimeoutExpection".

What should I do it?

Double check your local IP address that is running EXPO and look at the IP Address that EXPO is running on - these should match minus the port.

So for example, if your local machine has an IP of 192.168.0.210, EXPO should be Opening exp://192.168.0.210:19000. If they differ, you must change the EXPO environment variable for the IP address. Refer to React Native Expo change default LAN IP for that

  • So sorry for late reply. Firstly, I wanna thank you for your help. After fixing, my local mechine's IP and EXPO's IP address are the same. But, another error shows like this "Uncaught Error: java.net.ConnectException". What should I do? Thank u. – webdeveloper0-trying Dec 09 '20 at 03:12
