I had the same issue on my laptop during the weekend, message said issue was on their side, error 3006 iirc, couple of reboots from modem to pc as well as logging out and loggingbin on the app and it was pup again, I don't kniw whether something I did worked on they did something on their side.
Hi Guys if you get a ERROR 3011 on you Dstv now app where your channels don't work and you only get an black screen the problem isn't the app or Dstv but the ISP (Internet Service Provider) that needs to assign your router to a pppoe connection and not on automatic connection had the same problem and solved it
esampson is right. Its got to do with the fibre/wifi ISP. Its been working fine for years but all of a sudden not. It wont play off any of the devices connected to the home wifi but when i switch my phone to mobile data it plays no problem. call your isp.
