Hi there! It looks like you're encountering a "DNS could not be found" error when trying to access myTuner Radio. Let's work through this step by step to resolve the issue.

1. Check Your Internet Connection: First, ensure that your internet connection is working by visiting a few different websites. If those work, we can move to the next steps.

2. Clear Your DNS Cache: Sometimes, old DNS records can cause issues. To clear the DNS cache on your Windows 10 device, follow these steps:
- Press Windows + R to open the Run dialog.
- Type cmd and press Enter to open the Command Prompt.
- In the Command Prompt, type ipconfig /flushdns and press Enter. You should see a message confirming the cache has been flushed.

3. Restart Your Computer and Router: Restarting both can refresh your network settings. Unplug your router for about 30 seconds, then plug it back in and start your computer.

4. Change Your DNS Settings: If the problem persists, changing your DNS settings to use a public DNS server can help. Here’s how:
- Right-click on the Start menu and select Network Connections.
- Click on Change adapter options.
- Right-click on your active network connection (like Ethernet or Wi-Fi) and select Properties.
- Select Internet Protocol Version 4 (TCP/IPv4) and then 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 and then restart your computer.

5. Disable VPN or Antivirus: If you're using a VPN or any firewall/antivirus software, try disabling them temporarily to see if that might be causing the DNS issue.

If you've gone through all these steps and still encounter the problem, there might be a deeper network issue. In that case, feel free to reach out to your Internet Service Provider for further assistance.

Are you satisfied with the solution I provided, or is there anything else you'd like help with?
