OctoPrint Integration via Obico in HomeAssistant

Hello,
I’ve got up and running instance of HomeAssistant on my home network, additionally I’ve got different router on different than home network at the basement (LTE). I’ve got OctoPrint server placed in basement with connection to LTE network. I’ve already tried port forwarding in order to remotely access OctoPrint (no luck, seems operator block this option also security reason make me feel concern about that) I’ve decided then to install Obico plugin and this works pretty fine, I can access OctoPrint via tunnel see stats and progress. Nevertheless I still cannot configure HomeAssistant integration via this tunnel. I’ve tried to manually add Octoprint in configuration.yaml - unfortunately no luck with that either.

It’s my first topic therefore if I placed this one in wrong section please move it, thanks all for your help in advance!
