I too am finding an issue with my nabucasa remote access today. However, i can’t remember the last time i tried to access my HA instance outside network so i can’t say for how long this might have been an issue.
Dont know if this has any relevance or not, but today i found that both my dev HA instance and prod HA instances were autodiscovering the Spotify integration. I can’t work out how that happened because i didn’t have any active configuration for spotify, other than the pre-existing spotify developer app that is required. Some months ago i had created the config as per the integration guide, but disabled it again since i was not using it. In any case, today i did first install the integration in my prod instance where HA cloud is enabled. Then secondly, i switched to my dev instance & also installed integration where it too was successfully enabled. In both instances there was a nabu casa message indicating that the registration was successful.
Like i said, perhaps the spotify install has nothing to do with the remote access issue i see now. Tommy, did you by chance install the spotify integration prior to you discovering this issue?
This is the error i see. Is it the same for you?
I’m going to raise a support ticket via the nabu casa web site.
EDIT 2021-07-19: The day after this post the remote access started working again for me. Seemed a little slower than usual though.
