Not able to load octoprint WebUI from other device nor ssh connection possible

If've try to run octo4a on three different devices (2x Fire tablet & 1 cheap Android Smartphone). I was able to install on the Android phone as well as the older fire tablet. But I was only able to run octoprint on the older fire tablet. There I was'nt able to connect to the octoprint UI from another device on my network. I wanted to try the fix from this [post](https://github.com/feelfreelinux/octo4a/issues/205#issuecomment-1129345608) but I wasn't able to connect via ssh either.
