Error: getaddrinfo ENOTFOUND

[rduarte]

Hi, 

I've implemented a POC of an API proxy, very simple for a get operation and I was trying to invoke it via Postman and/or browser.

When trying to invoke the proxy I am getting the error "Error: getaddrinfo ENOTFOUND ". 

I took the hostname from the environment groups and even tried to force a hostname through Domains in the settings portal, however the error is always the same.

Can anyone help me with this DNS issue please?
