I think this error was a failure in DNS name resolution. The application was trying to call an API but it is not able to find the hostname.

Your server should be able to access to the DNS server. Additionally, your DNS server should be able to lookup the hostname that is in your code. Troubleshooting steps: Run ipconfig /all in Command Prompt. Fin the IP addresses of the DNS server in the output. Try to ping it.
