Description

Since upgrading to RN 61, I haven't been able to properly open my app on Android.

When I try to run the app with react-native run-android, the Metro bundler does not launch automatically.

When I run Metro with npx react-native start --reset-cache, it runs on port 8081 and loads the dependency graph but it doesn't bundle when I attempt to run the app on the CLI. It seems to behave like this in debug and release environments.

Any insight would be greatly appreciated!

Steps I've tried

• npx react-native start --reset-cache
• watchman watch-del-all
• watchman watch-del-all && rm -rf node_modules/ && npm cache clean && npm install && npm start --reset-cache
• brew uninstall watchman && brew install watchman
• delete node_modules, npm install clean project, rebuild project, invalidate caches / restart.
• migrating my node_modules to AndroidX

I believe we're experiencing the same issue on iOS.

App builds fine. Then Flipper shows that app makes an initial status check request to metro, which resolves with a 200, no problem, but then subsequent request for bundle appears to time out...

This appears to be 'machine-specific' to one developer on my team and affects dev's ability to work on all existing and or new apps. Timing seems to coincide with upgrade to latest MacOS. On other hand, my machine is also up to date with updates and I have no problem.

same issue here. For my colleague it works fine, for me it doesn't. Can't run any app since updating to RN 0.62.2.

FWIW, we ended up having to completely wipe the affected dev's machine to fix...

try cleaning gradlew and remove node_modules and then reinstall it........ it may work

It's happening to me again...
