Failure "Cannot GET /link/9acc7Bf002B8D3cc9cA1ddca2BBBAe97"

[Jaques-Ludwig]

I tried to connect Hue Essentials with hass-emulated-hue.

The App asked to push the button on the bridge and I get a message in Home Assistant. But if I use the link in Home Assistant I get the message in my browser:

"Cannot GET /link/9acc7Bf002B8D3cc9cA1ddca2BBBAe97"

Can someone help?

Thanks,

Stephan

Ok, I started all new (Home Assistant, Emulated Hue), deleted App-Data of Hue Essentials.
I saw, that hassio_observer in mei container list was on Port 80. I switched it to 82 and now all works.

Be aware that using ports other than 80 and 443 will result in unexpected behavior in some apps. As additionally, not using host networking results in discovery not functioning.
