My leviton dimmer switch stopped working from the home app

[hepcat72]

I have an automation that turns on a flood light using its homebridge representation when I arrive home. It's been working flawlessly for over a year, but tonight it didn't turn on. The Home app claimed it was on, and I noted that even using the button in the home app (toggling it on & off), it won't change the light's actual power state. The Leviton app itself works.

So I checked the homebridge log and it has the following error:

(node:783) UnhandledPromiseRejectionWarning: FetchError: request to https://my.leviton.com/api/Person/login?include=user failed, reason: getaddrinfo EAI_AGAIN my.leviton.com

To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 3)

What is causing this to happen? How do I fix it?

I just tried a test on the command line, and I didn't get a rejected response, but the home app still isn't effecting actual state changes. I'll look deeper later, like try a homebridge restart or something...

It just randomly started working within 24h, so I'm going to chalk this up to a leviton server issue.
