Some blink servers have expired certificates.

A user of my homebridge plugin noticed that some blink servers have expired certificates which causes API calls to fail using this plugin. You can see the discussion here. homebridge-plugins/homebridge-blinkcameras#28 (comment)

There’s also a discussion of this over here for homeassistant home-assistant/core#24221

Looks like it might have to do with a change in how the URLs should be constructed. See MattTW/BlinkMonitorProtocol#39 (comment)
