getting java.lang.RuntimeException: java.net.UnknownHostException in REST Connector
I am trying to connect an Open source API to get Address by Postal Code through a REST Connector. I am able to see the result in web browser but while connecting from PEGA getting the below error. there is no authentication for this API.
Caught unhandled exception: java.lang.RuntimeException: java.net.UnknownHostException: This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server (api.postcodes.io)
example: https://api.postcodes.io/postcodes/NE30 1DP
