The error you're encountering when trying to log into Unity on your Xbox 360 and receiving an error about not being able to get the API key might be due to several reasons. Before troubleshooting further, make sure that Xbox Live is operational and not experiencing any outages. Sometimes, login issues can be related to Xbox Live's status. Additionally, if this issue persists, it's worth considering the possibility of a B2B API integration problem between Unity and Xbox Live, as such integrations can also impact the retrieval of API keys and authentication processes.
