HA-Fusion not reachable outside my network

[canedje]

I opened soem time ago this issue: #89

I just did find out the solution:
At the docker settings you need to define home assistant URL as: https://your external Nginx URL
I did use first http://your external Nginx URL
That is not working

UPDATE:
Sorry.
above is only working on a PC.
I tried on my android mobile and iPad, then it is showing a white screen
