A few days ago my Alexa Smart Home integration stopped working. I tried disabling and re-enabling the skill in the Alexa app and via the website and it will not re-link. When trying to link, I’m prompted for my HA login/password, it seems to accept it, but then gives me an error stating Unable to link Home Assistant to Alexa.
It seems like Alexa isn’t getting the token or something. There is no associated token entry in the profile section of the HA app. There aren’t any useful entries the HA log either. Any ideas? There’s no way it’s related to the Let’s Encrypt root CA expiration from a few days ago, right? I only mention because I hadn’t changed anything or even restarted HA when the problem first presented itself. Thanks!
