> If i have a RPG configured to use the RAW transport protocol and then switch it to use HTTTP transport protocol, it will throw the following error message twice before finally correcting itself:
> 2017-01-19 22:10:32,363 ERROR [I/O dispatcher 841] o.a.n.r.util.SiteToSiteRestApiClient Failed to create transaction for http://<hostname>.openstacklocal:8055/nifi-api/data-transfer/input-ports/b76c293d-0159-1000-0000-00003f85f297/transactions

> Similarly the following ERROR message will be thrown many times when switching from HTTP to the RAW transport protocol:
> 2017-01-19 22:13:15,916 ERROR [Timer-Driven Process Thread-10] o.a.nifi.remote.StandardRemoteGroupPort RemoteGroupPort[name=outport2,targets=http://<hostname>:9090/nifi/] failed to communicate with http://<hostname>:9090/nifi/ due to org.apache.nifi.remote.exception.HandshakeException: org.apache.nifi.remote.exception.ProtocolException: Expected to receive ResponseCode, but the stream did not have a ResponseCode
> With both these scenarios, the RPG will eventually correct itself and start working again. User may be hesitant to wait once they start seeing these ERRORS and instead stop the RPG since the self correction does not occur rapidly.
