I have the exact same problem as here: Network Response Time Out Error (create-react-native-app) (expo). Every time I try to scan the QR code from my phone on LAN, I get the network response timeout error.
I've gone through every single response in both the linked stackoverflow post and the associated github thread: https://github.com/react-community/create-react-native-app/issues/144#issuecomment-296631692 to no avail.
Everything I've tried
- set REACT_NATIVE_PACKAGER_HOSTNAME='my-custom-ip-address-or-hostname' with my static ip
- disable all connections aside from my wifi (The only other connection I had to disable was "Local Area Connection 4", I didn't have virtualbox like others)
- set my wifi connection to private
- completely disable windows firewall
- make exceptions to 19000, 19001, 19002 (entirely redundant given I disabled firewall, but I was desperate)
- restart computer multiple times
- use same network on phone as on computer
- put the line,
"android": "set REACT_NATIVE_PACKAGER_HOSTNAME={your wifi ip address} && react-native-scripts android"in my package.json
Note: A friend on the same network (also using a windows 10 laptop) got expo over LAN to work perfectly fine to his phone, so it's probably specific to my computer.
Note #2: Tunnel qr scanning works fine, but is painstakingly slow to reload so not realistic to use. Local brings me directly to "Something went wrong", no timeout error.
