Hello,
I followed this tutorial:
https://docs.apigee.com/api-platform/get-started/create-proxy
That shows how to create a "Hello World Proxy". I followed the document Step by Step, and at the final, i have a proxy, but when i try to access the Proxy Address i receive a "An error occurred. Sorry, the page you are looking for is currently unavailable. Please try again later." (I'm pointing the proxy to http://mocktarget.apigee.net as explained at the tutorial, that is a URL that works accessing directly).
What happened?
