> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Andre F de Miranda
>
> In testing the patch provided for NIFI-868, I set the nifi properties to
> advertise the hostname as "otherhost". Site-to-Site, of course, failed to
> connect, but rather indicating that it could not connect to otherhost, it
> simply indicated that it was the RemoteProcessGroup connected to
> http://localhost:8080/nifi. This is misleading because it leads the user to
> believe that the Remote Process Group is having trouble connecting to
> localhost, when in reality it is attempting to connect to "otherhost". We
> should indicate which host we are connecting to when providing an error like
> this.
