Hello @arpanaarora.934! Adding another crucial layer to the discussion about accessing local web servers from physical Android devices! Your initial query about the 10.0.2.2 address is something many mobile testers encounter.
This setup is very much a part of our regular mobile testing workflow. One absolutely critical thing to add to the troubleshooting list: make sure any firewalls on your machine (like Windows Defender or macOS firewall) allow incoming traffic on the specific port you’re testing (e.g., 3000 or 8080). These often silently block those connections, causing massive headaches.
Also, I always make it a point to verify both devices are strictly on the same subnet. Weird connectivity things happen when one’s connected via a VPN or a guest Wi-Fi network that isolates devices.
Hope these additional checks help you pinpoint and resolve any lingering connectivity issues!
