This looks like your cookie file has expired. Delete and relogin. If you are using config flow, you can just remove and readd the integration with no need to restart.

I'll separately figure out why it's not properly forcing a relogin when it sees this.

After restart HA there are no errors in log and component works without relogin or any other action.
