Hi. I have a mag 256 and have received a free trial for IPTV. I have never used one of these boxes before. I am unable to get it set up. I have the box linked to wifi and in the Portal URL i have entered the details given by the provider. I saved and then rebooted and tried restarting also but message comes up that STB is blocked. I know i am doing something stupid or not doing something possibly. If anyone can help please. Thank you.
