Hey there!
Google didn´t help so maybe community will 
I have HA instance running on RPi3b+ at my dad´s house. Everything was working correctly and also trial version of nabu-casa work well. After trial I subscribed so I can maintain it remotely for him. However during week HA was without subscription something went wrong and after subcribing in HA settings under title “Home Assistant Cloud” I got stucked with text “Fetching subscription…” and nothing changed even after hours. So I tried to unlink nabu-casa account and add it again but I got red text “Unable to reach the Home Assistant cloud”. I tried fresh instalation but it still “Unable to reach…”. HA instance is obviously able to connect to the internet as it downloaded all addons correctly. I think that it´s some kind of local network or router issue but I really don´t know what should I be looking for in router configuration. Anybody any idea? system log below.
Btw. it´s not that big issue as HA was mainly for heating regulation and that works great locally but my dad “got thing” for this whole home automation universe and started ordering smart lights and cameras so now I´m this ambitious son who brough something to the home and is unable to fix it [desperate-face-emoji]
