The ssl certificate used by the redis service does not include * as a subject alternative name. Instead it has configured twice.

    As documented here:, {cachename} is a canonical name to {cachename} and it is recommended to use {cachename} in all client applications/connection strings. We will update our documentation with this recommendation. Please note that the private DNS zone that is created in your subscription is vital for TLS communication and should not be removed.

    Hi @David Noriega Thank you for being patient while working on this issue.
    Could you please try using the * hostname rather than * Let us know if that works
    We will also update documentation to be more clear.
