Problem connecting Tvheadend outside local network

[nickiman]

Hi,

I´ve installed webos-tvheadend via web manager desktop app in my mother´s home TV. The details of my TV are:

Device - 32LQ63006LA
Firmware version: 04.40.91
webOS version: 7.4.0

I´ve been trying to connect it with my server running at my home without success:

The address used is http://mydnsaddress:externalport
The port is not the default one 9981 I´ve changed it for another one and point it internally in my LAN to 9981. I mean:

(WAN) http://mydnsaddress:externalport - (Router N.A.T.) - LANaddress:9981 (LAN)

Tvheadend has this configuration in Authentication type:

And the user which I´m trying to connect, has this configuration:

I´m getting these errors:

These errors with a different firmware version were the same with the above firmware versions mentioned

What I´m making wrong?

The error you are getting has actually nothing to do with the network connection. It indicates that the proxy service of the app did no start.
Some users reported that on mostly newer TVs. Unfortunately I don't habe the possibility to debug and test it without such devices.
Maybe there is someone with the same/similar error/device who can help out?

If you need some log or file content, let me know how to get it and I´ll try to provide you to make the debug and tests.
