Playback error: response code 502

Using Amazon fire stick. Constant buffering and now this error and screen freezes. This error occurred on live tv, however buffering happens both live and recorded. Have change quality to 720 (3mps) with no improvement. Works fine on iPad app. Fire stick successfully plays other content with no issues, so it seems to be an issue specific to the fire stick Tablo combination. Anyone else solved this?

Have you tired rebooting the router, waiting 2 min, rebooting the Tablo, waiting 2 min, then rebooting the Fire TV Stick?

I’m having a similar problem with the Fire TV box thing… not the stick. Except, I get Response code: 404.
