kodi 17.3 and npvr on firetv not working

Hi all,

This is my setup.

TV1 connected to Computer running windows 10. This has an antenna being fed into it. I have my NPVR server here as well as Kodi 17.3 for windows. NVPR works fine through Kodi,

TV2 connected to fireTV. I have kodi 17.3 for android installed here with NPVR as the DVR client. It worked fine until I upgraded to 17.3. I have uninstalled and re-installed several times, read other threads, etc.. I have the correct IP address and port configured for npvr. Every time I enable it though I get a pop up saying “unknown error occurred”

It’s clearly not the NPVR service since it works fine and I can use it as before with the windows version of Kodi 17.3. It’s just the android version on my fireTV that is giving me the issue. Any suggestions?
