Multiview not seeing Plex OTA Channels

I have a Plex server located in a good antenna location to receive OTA stations on a remote network. All of my Plex clients work without issue viewing these channels. Trying Multiview, it seems I am able to login and link my phone or AppleTV and Multiview shows the FAST channels, but no OTA channels. I am linking with the admin Plex account so I don't think it is a permission issue.

I do have an openvpn connection between the two sites and I can use Multiview if I add the HDHR-Quatro directly. Video and audio plays without issue, quite responsive actually. Trying to access those same channels via the Plex protocol on the remote server does not bring back any OTA channels. I even created another Plex server at my location (same subnet as iPhone or AppleTV) using the same Plex login credentials and added the HDHR DVR through the VPN. Via the Plex app, the OTA channels play without issue. When I attempt to access the channel list of the local Plex server, Multiview indicates there are none. FAST channels work but OTA does not.

What am I missing? I apologize if this has been covered already. My searches did not reveal any answers for me.
