Frontend not starting

Hey guys - I am on the beta channel for hassio, and yesterday I did the update to 0.101b2. Since then, the the hass container starts, and from what I can see in the logs, the backend seems to be loading correctly, but the frontend never loads. Other hassio containers (e.g. nodered) are up and responsive. Additionally, I have tried restarting the hassio container and the supervisor container (just in case), but no luck… Not sure what the problem is… Lots of this in the logs…

The beta discord channel is where the bleeding edge support happens.

Thanks. I posted, but was too impatient for an answer. I ended up editing the updater.json file and moving it back to the stable channel and 0.100.3.

I am getting the same error too and it seems to have to do with Alexa Notify addon. So you say you edit updater.json file what did you edit in it?
