I'm using IntelliJ IDEA to implement the Spring Guide for consuming REST services
https://spring.io/guides/gs/consuming-rest/
When I run the Application class I receive the following error
Exception in thread "main" org.springframework.web.client.ResourceAccessException:
I/O error on GET request for "https://gturnquist-quoters.cfapps.io/api/random":
gturnquist-quoters.cfapps.io;
nested exception is
java.net.UnknownHostException: gturnquist-quoters.cfapps.io
The URL itself (https://gturnquist-quoters.cfapps.io/api/random) opens fine in a browser and my HTTP Proxy settings in IntelliJ can connect to the site without any issues. Why would an UnknownHostException be thrown here?
