Getting Unknown host URL exception for Corda Doorman

Question

I am planning to generate a certificate and register the identity of the node in Corda network. I have used this URL http://testnet.certificate.corda.net but it throws an exception if I trigger the command (java -jar corda.jar) with --initial-registration.

This is the stack trace:

Submitting certificate signing request to Corda certificate signing server.
Exception in thread "main" java.net.UnknownHostException: cordaci-netperm.corda.
