If a satellite organization states 'satellite organization does not exist' along with a 401 error, what could this imply?

This specific combination of 'satellite organization does not exist' and a 401 Unauthorized error is unusual. It could imply that either the endpoint you are trying to reach doesn't exist (perhaps a typo in the URL), or the organization identifier within your request is incorrect, leading the system to not find a matching entity to authenticate against. It might also suggest a misconfiguration on the server's side where it's incorrectly reporting a non-existent organization as an authentication failure.
