> With a new install, from 'master' branch I created an Input Port and then a Remote Process Group pointing to localhost:8080/nifi. When attempting to send data to my Input Port, nothing appears to happen in the UI. In the logs, I see the following:
> {code}
> 2017-11-22 09:30:39,918 WARN [NiFi Web Server-184] o.a.nifi.web.server.HostHeaderHandler Request host header [<hostname>.local:8080] different from web hostname [localhost(:8080)]. Overriding to [localhost:8080/nifi-api/site-to-site/peers]
> 2017-11-22 09:30:39,918 WARN [Http Site-to-Site PeerSelector] o.a.n.r.util.SiteToSiteRestApiClient Failed to parse Json. The specified URL http://<hostname>.local:8080/nifi-api is not a proper remote NiFi endpoint for Site-to-Site communication. requestedUrl=http://<hostname>.local:8080/nifi-api/site-to-site/peers, response=<h1>System Error</h1>
> <h2>The request contained an invalid host header [<hostname>.local:8080] in the request [/nifi-api/site-to-site/peers]. Check for request manipulation or third-party intercept. </h2>
> {code}
> I tried updating nifi.properties to set the "nifi.web.http.host" property to <hostname>.local and that did resolve the issue... but then I could not connect to the UI using localhost:8080 but instead had to connect using <hostname>.local. 
> This appears to not affect any released versions of NiFi.
