This error typically occurs when the host or address provided cannot be resolved by the DNS server. The DNS server is responsible for resolving domain names to IP addresses.

To troubleshoot this error, you can try the following steps:

1. Check that the host or address you are using is correct and valid.
2. Check that your internet connection is working properly.
3. Try using a different DNS server, such as Google's public DNS server (8.8.8.8).
4. Check your firewall settings to ensure that the application is allowed to access the internet.
5. If none of the above steps work, contact your network administrator or internet service provider for further assistance.
