I found out that it was widespread outage at the Tablo servers. It was back up when I checked later.I had the same thing happen yesterday on my Fire Tv in the office. It didn't recognize my Next Gen Tablo so I rebooted the TV and then deleted the Tablo app and readded it and then I was able to see my Tablo. Quirky behavior. My old legacy Tablo was always connected with no problems.
