am new to React native Expo I need to add some new modules on my project. "expo": "33.0.0", "react": "16.8.3", whenever I try to run my project am getting Error am not able to run the project. I tried all way to run the project like set REACT_NATIVE_PACKAGER_HOSTNAME='192.168.0.102', firewall off, allowed inbound 19000 port etc. but am getting error.

when I enter expo start -c

 Your project may not work correctly until you install the correct versions of the packages.
To install the correct versions of these packages, please run: expo install [package-name ...]
Starting Metro Bundler on port 19001.
Your JavaScript transform cache is empty, rebuilding (this may take a minute).
Your native app is running at exp9c305c55e38f4d0e856f59397620314e://192.168.0.101:19000
Logs for your project will appear below. Press Ctrl+C to exit.

then my laptop and mobile is connected with same network and same IP but am getting error and i don't know the port 19000 is different from my wifi

Uncaught Error:java.net.SocketTimeoutException:failed to connect to/192.168.1.20(port 19000)from/192.168.0.102(port 49615) after 10000ms

Please give some solution for it.

it's fail because port 19000 is not open in your firewall if you use linux OS open this port by sudo ufw allow 19000/tcp

enter image description hereFirst Check are you in tunnel connection? If you are in tunnel connection then

First : ipconfig

then : set REACT_NATIVE_PACKAGER_HOSTNAME=192.168.1.103 (IPv4 Address)

then:npm start

It worked for me. Hopefully it will help.

I resolved this by changing the network profile on the connected wifi from private to public.
