Expo app on Android can't connect to LAN

Today I was working on my app through the Expo app on my physical Android device. I leave the house to run an errand, and when I come back and start expo back up it suddenly won’t connect, showing “Something went wrong” and “Uncaught Error: java.net.ConnectException: Failed to connect to /”.

I then try using the Tunnel, and it works. However, when I turn on Debugging it breaks the state, so that isn’t an option.

I’ve also tested Expo on a different phone running on Android 10 (the one it doesn’t work on is Android 9). Both are on the same network, yet the Android 10 phone works. I’ve tried clearing storage/cache, resetting the network, and restarting my phone yet none of these worked. What could be the issue?
