who knows what server collects from your device like device id, IP address...etc to keep you safe from cloning your Mac. but whatever is I personally think its good thing since its very easy to find your credentials lol
I guess it might be due to security reasons from your tv provider which I would say is good thing just incase someone try to login with your credentials without your permission.
same here reset two units last night and no issue connecting all. reason for reset was having connectivity issue in friends house and later found it was his wifi6 new router causing issue. replaced with old router and no issues.
your firmware is up to date but iptv not. while watching live tv press menu, settings, check for updates and see if it downloads version.794. if not then send a pm to allaboutbuzz with your box, Mac and serial number and ask him to send you update.
