If anybody comes across this post with a similar problem , I have come to the conclusion that the real culprit here is my router
Router is a sky q 2.4 and 5 ghz
Reason I think it’s the router is that my harmony iPhone app stopped working and wouldn’t connect , spent about an hour playing with the router , app starts working again and so does hassio
Suspect it will stop working again so may need to look at replaincg the sky q router
