--------------------------+-----------------------------
 Critical issues report when using a localhost server that does not resolve
 to a real domain that is publicly accessible.

 In both cases below this is not correct.

 ----

 __1: The REST API encountered an error__

 '''The REST API request failed due to an error.
 Error: [] cURL error 6: Could not resolve host: dev.example.vm'''

 The host resolution issue is not an error. Localhost domains can never
 resolve to a public nameserver.

 ----

 __2: Your site could not complete a loopback request__

 '''The loopback request to your site failed, this means features relying
 on them are not currently working as expected.
 Error: [] cURL error 6: Could not resolve host: dev.example.vm'''

 Loopback requests work fine, there is no error, it's just a localhost
 domain
