Mag254 Your STB is blocked call the provider - You may see this error message displaying on any IPTV boxes or STB emulators that is being use in a compatible device. Some of the reasons that may trigger this message are; an expired account, incorrect portal or URL address linking to your STB, and a banned mac or ip address, just to name a few.
One of the solutions to fix it could be as easy as rebooting your devices, if this doesn’t work then maybe you just need a re-authorization of the service, which in many cases it could be done by yourself or by asking the person who created the account to do it for you. Assuming that your donation or service is not expired.
