Hello @Prem Kothawle , Thanks for using Microsoft Q&A Platform.
This error can occur due to various reasons, such as network connectivity issues, DNS configuration problems, or firewall restrictions.
Try to check your network connectivity: If you are behind a firewall or proxy server, make sure that it allows outbound connections to the Bing search API endpoint.
Verify the DNS configuration: Check if the DNS server settings on your device are correct.
Please re-try the API call and also share more details with us.
