Firebase for android not working in my test device suddenly

Question

I am building an app with Firebase Authentication and Realtime Database. Before yesterday, it was working cool in my device while testing. But I am not able to even login with Firebase now, but the app is working on other devices of my friends.

What is the actual issue here ? Is there any limitation for testing app your own real device? Is some kind of limitation exceeded ?

I tried uninstalling the app and reinstalling, removing user account from firebase database. But still no work.

Thanks!!

In my case, it would work on an emulator but not on my actual device. The solution was resetting my WiFi router. I don't know why it worked but it did. This answer helped me: Firebase database listeners don't work on android with wifi
