We ejected our app a while ago from expo and everything was running fine since then. We managed to add native libraries and upload our app to TestFlight and google play for internal testing. Today we’ve ran into a huge issue that we couldn’t find any solution to.
Whenever we tried to install a new .apk file for android built from Android Studio it would constantly keep crashing with no error. We have Sentry set up in our project, so we would’ve gotten a crash report if it was from our side of the code. The project runs fine in development and production mode from the emulator or if I connect my phone to android studio. Running adb logcat *:E and checking the phone’s crash suggests the following fatal exception:

We’re not sure what “Expo encountered a fatal error: javax.net.ssl.SSLHandshakeException: SSL handshake aborted: ssl=0x7c9a4e1e08: I/O error during system call, Connection reset by peer” means or what expo is trying to establish an SSL handshake with.
We’ve spent the entire day searching google for anything related but we’ve hit a roadblock. We even tried creating a fresh expo project and then ejecting and building the .apk and it still throws that error on physical phones. Non-ejected apps work fine and our same iOS ejected app also works fine.
What we noticed is that this error will keep popping up after a fresh install of the app on most WiFi connections, and we can get past it by using a VPN, using the phone’s mobile data while crash the app a couple of times or not at all and then it would work fine. After that the error never comes back again, even without a VPN or when using WiFi. Unless we uninstall the app and install it again, the error would keep showing and crashing the app with a WiFi connection with no VPN.
So we think it has something to do with the connection that Expo is trying to establish but we don’t know what it is.
Disclaimer:
We’ve been having trouble with Expo’s server-based services such as ‘expo publish’ and ‘expo start’ always returning a
Fetching the user profile failed
read ECONNRESET
errors (even from way before ejecting) that we can only get past by with using a VPN and some days it would work fine, so we think that might be related.
