Suddenly having issues logging into the Cloud Service

All of the sudden, I can’t log into the Nabu Casa cloud service via Configuration -> Home Assistant Cloud.

When I enter incorrect credentials, I receive “Authentication failed” error text (as expected). When I enter correct credentials I receive “Unknown error” error text. So it’s definitely distinguishing between valid and invalid credentials. But my logs indicate that there’s an issue with the token it’s trying to assign me:

2019-01-13 09:01:05 ERROR (MainThread) [aiohttp.server] Error handling request

During handling of the above exception, another exception occurred:

From reading the logs, it sounds like (not 100% sure) Nabu Casa needs to update their security certificates? But I’m not sure if I’m reading it right…

Anyone else run into this issue or have a better interpretation of the logs?

Thanks in advance.
