Fix UnknownHostException

✅ Solution

The "UnknownHostException" typically arises when the Firebase SDK cannot resolve the hostname it's trying to connect to, usually due to network connectivity issues or DNS resolution problems. Ensure your device or emulator has a stable internet connection and that your DNS settings are correctly configured. You can also try clearing your DNS cache or switching to a different DNS server (like Google's 8.8.8.8) to resolve the issue.
