Flutter Taxi App Urgent Issue Fix

I have a Flutter-based multi-purpose taxi application with a Laravel backend, currently hosted on a VPS. An urgent issue has arisen: when a user requests a ride, the request fails to appear on the driver app. The driver app is confirmed to be consistently connected to the internet, and there are no error messages or logs when a ride request is made.

I need a professional with strong expertise in Flutter and Laravel to help diagnose and fix this issue as soon as possible. Time is of the essence.
