As of 2024-05-14 a change has been implemented to enforce access token expiry. If you see higher numbers of HTTP 401 responses, please check tokens that may have expired. For more details, including how to mitigate disruption, please check our docs guide on Expired Access Tokens. If you have a support contract, you may open a support ticket for additional assistance.
Looks like this part of the documentation has been copied and wasn't corrected. The description references the global.ingress.tls.secretName and a serviceName doesn't make much sense here so I think this should be tls.secretName.
