Cloud integration suddenly broke

I noticed I wasn’t able to connect to my HA using the nabu casa link any longer. So I tried using my ddns and that worked. When I check the logs there are all sort of errors referencing python scripts related to nabu casa and other cloud components. I havent made any changes to my config. My current core version is 2021.11.5 and the supervisor is 2021.10.8. These are the errors Im getting. Any ideas where I can start troubleshooting?

Do a forum search. There are a lot of reports of issues with Nabu Casa right now.

I did. Lots of searching. But only found old config issues, docker issues, version issues etc… But I may have been searching before people started to post about this issue. But thanks for the info. Good to know. Someone else shared my post on someone else’s post asking the same thing.
