> 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.
