payama Hello.
Thank you for the request!
A box receives such a message from an external portal of your IPTV/OTT service provider or operator. Most often it means that your model of the set-top box is not in the list of allowed STBs for connecting on the provider's portal. In this case, it is necessary to contact your provider and find out whether your set-top box model is supported by their portal.
Kind regards,
Infomir's team
