I was getting the same thing a couple nights ago. I was watching on a Roku Premiere and would have to exit out of the racing feed and then get back in. I haven't seen it happen since then so I'm assuming it was a glitch.
Broadband is world's away from the dial up days. But with more devices accessing your breadboard / modem than ever a couple of simple weekly maintenance tasks can do wonders.
1, Reset / reboot your modem, unplug count to 10 plug back in.
2, reboot streaming device (firestick / Roku) unplug count to 10 plug back in.
Doing this quick and easy maintenance will remove any data clutter than may be slowing down your internet speed and device.
Try it.
It's not the No.1 thing to do on the I.T repair manual for nothing.
