Recently we have noticed that routers with inbuilt security such as Trendmicro or Bitdefender had automatically started blocking the streams from working.

In order to resolve this issue please log into your router and deactivate your security software. If there is more than one option available then turn them all off and then back on one at a time and check of tour streams are back. Ensure to reboot your box if the streams are back and recheck before turning other options on.
