Hi there! I see you're encountering the error message "A server with the specified hostname could not be found" while using the Raaga app. I'd be happy to help you get this sorted out.

To start, this error generally means your device is having trouble finding the server address it needs to connect to. This could be caused by DNS (Domain Name System) issues or network configuration problems.

Here's a step-by-step approach tailored for your Windows 10 setup:

1. Check Internet Connection
Make sure your internet connection is working correctly by opening a website like www.google.com in your browser.

2. Flush DNS Cache
Sometimes cached DNS data can cause issues. Let's clear it:
- Click the Start menu, type cmd, right-click Command Prompt, and choose Run as administrator.
- In the command prompt window, type: ipconfig /flushdns and press Enter.
- You should see a confirmation message.

3. Set DNS Servers to Google DNS
Since DNS might be the culprit, try setting your DNS servers to Google's public DNS:
- Open Control Panel > Network and Internet > Network and Sharing Center.
- Click on your active connection (like Wi-Fi or Ethernet).
- Click Properties.
- Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
- Choose Use the following DNS server addresses and enter:
- Preferred DNS server: 8.8.8.8
- Alternate DNS server: 8.8.4.4
- Click OK to apply the changes.

4. Restart Your Computer
After changing DNS, restart your PC to ensure changes take effect fully.

5. Try the Raaga app again and see if the problem is resolved.

If this doesn't solve the issue, it could be related to your network environment or a server-side problem. Let me know if you happen to see this error only on a specific network or at all times.

Does this help fix your Raaga app issue? If not, I’m here to assist you further.
