At coldroom-claim- [removed by moderator] .us-central1.run.app, I was issued Tenant 48. However, although my credentials are accepted, I am unable to authenticate, for I observe:

400. That’s an error.

There may be an issue in your organization’s identity configuration. Contact your admin or try again.

Additional details

Verification failure: invalid session ID in request.

If this is the correct place to ask, what may be the cause, and [how] can it be resolved? If that is infeasible to ascertain on your end, how should I diagnose this? If I should ask elsewhere, where?

Can you try using an incognito window? Are you already signed into another Google account in the current window?
