To resolve the issue of "network failure" with Lura, you can follow this detailed step-by-step guide:

Check Your Internet Connection

1. Ensure you have a stable internet connection:
- Verify that other apps or websites are working on your iPhone.
- If you are using Wi-Fi, check the signal strength and make sure you are connected to your network.

2. Test your internet speed:
- Use internet speed test applications to ensure your connection is not too slow or unstable.

Restart Your Device

1. Power off your iPhone completely.
2. Wait for about 30 seconds, then turn it back on.

Check For App Updates

1. Open the App Store on your iPhone.
2. Tap on your profile icon in the upper right corner to access your account.
3. Scroll down to see if Lura has any pending updates. If yes, tap "Update".

Reinstall the Application

1. Long press the Lura app icon until the menu appears.
2. Select "Remove App" and confirm the deletion.
3. Go to the App Store, search for Lura, and reinstall it.

Reset Network Settings

1. Open the Settings app.

Disable VPN or Proxy Settings

1. If you're using a VPN, it might interfere with your connection:
- Go to Settings > VPN and toggle it off.
2. Also, check if there are any proxy settings enabled that might restrict the internet connection.

Check Server Status

1. Sometimes, network issues can arise from the server side:
- Check if there are any known outages or maintenance schedules for Lura by looking through their social media channels or official website.
