Its been a few days that Blink integration has been broken for me, it seems to be an AuthN issue as I am getting an Unexpected error when trying to re-configure the integration (was working fine for months). HA log says:
2026-03-17 06:02:03.554 ERROR (MainThread) [blinkpy.auth] Connection error. Endpoint https://api.oauth.blink.com/oauth/token possibly down or throttled. Error:

I only use this integration for getting the cameras' outside temps.
I am running an older HA core: 2025.11.0
