All my Sky Q mini boxes have the error message and won’t work

[Thomas279]

@Sky  My main Sky Q box is working but all my mini boxes have the same error message: "Please check your subscription entitles you to view this channel on this box. Otherwise, if you're using this box for the first time, please wait a few minutes."

It is there on every channel. I have tried resetting and rebooting and unplugging etc. multiple times and nothing works.

Please advise what I need to do to fix this?

Many thanks, Thomas
