Splunk Stream: Why does my heavy forwarder not show up in the Distributed Forwarder Management?

Hi, I'm about to pull what little hair I have left out. I have a SH and Indexer Cluster running 6.5.1. My cluster uses our own SSL certs for server.conf, web.conf, and inputs.conf, which appear to be working fine. I've installed Splunk Steam (splunk_app_stream and Splunk_TA_stream) on my deployment/admin server. I've installed Splunk_TA_stream on my indexers and a heavy forwarder. I set the location of my server running the splunk_app_stream in the inputs.conf and the Splunk_TA_stream on the heavy forwarder. My problem is that the heavy forwarder still does not show up in the Distributed Forwarder Manager even though I see 2 way traffic via tcpdump. Can anyone help me who has set this up before? What information do you need? Thank you so much in advance, Todd
