Tvheadend

I have recently configured a RPi 3B (v 1.2) with OSMC (running KODI 20.1) and TVHeadend 4.2.8. My intention is to use this for viewing video/movies (stored on a 256G thumb drive) and OTA TV viewing at our remote camp. All software installed, configured, and appears to operate fine at my primary residence. At my remote location, I will need TVHeadend to rescan for available channels. I am able to receive several OTA TV broadcasts, but do not have access to internet or wifi.

At my remote location, I was able to activate an OSMC 'HotSpot'. The 'HotSpot' was visible on my tablet, and I was able to logon. My assumption was that as OSMC and TVHeadend are loaded on the same computer, TVHeadend could be accessed through IP 127.0.0.1. However, I was unable to access TVHeadend through 127.0.0.1. For some reason, my TVHeadend instance thought its' IP address was 192.168.0.1. While I was able to logon to TVHeadend using this (192.168.0.1) IP, a channel rescan was unsuccessful. I fear some parameter is misset.

Subsequently (back home), I note in TVHeadend (Status>Users) both my home (network) IP and 127.0.0.1 are listed as users. However, both have a red stop sign containing a white x. Does this indicate 'inactive'? If so, how do I activate. How can I get TVHeadend to communicate with OSMC through 127.0.0.1?
