It looks like certificates are getting mixed up somehow. The upgrade is triggered and machine-0 reboots into the new tools version and then it looks like the certificate for API server access is being used for connecting to MongoDB! (or something)
Because the state server can't connect to MongoDB the environment can't come up.

I'll keep digging into the cause.
