Nginx Proxy Manager

There is tvheadend on the local network (ip address 192.168.100.119). To watch IPTV on the local network on KODI in the Tvheadend HTSP Client settings, I configure only the server's IP address 192.168.100.119 and everything is fine.
I need to configure IPTV viewing regardless of location.
I am trying to configure Nginx Proxy Manager to access tvheadend at tvheadend.mydomain.net. In my browser, at tvheadend.mydomain.net, I can access the web interface of my home Tvheadend server (port 9981). But if I enter the address tvheadend.mydomain.net in the Tvheadend HTSP Client settings, I am unable to watch IPTV. Can someone help me with the settings?

I changed some settings in the Tvheadend client Kodi (changed the HTSP port to 80), now I get the error "Server does not respond properly"
