Just trying to set this up for my new 2022 Bolt EV! Looks like a connection problem trying to login?

It unfortunately looks like they changed the front page again, so the way to get into the environment fails again.

I appears that https://github.com/samrum/OnStarJS and https://github.com/mikenemat/gm-onstar-probe have figured out a more direct route to the onstar API. That's probably worth investigating.
