Definitely not my home network. I have multiple services such as emby, plex and rdp allowing access to my network. Tablo was the only service that went down. I was still able to connect to all my homes services with no issues. Also, when this happened, the Tablo channel in my plex server would not stream however plex would stream perfectly. When remoting into my home pc, thats on the same network as the Tablo, it was taking abnormally long to sync the Tablo to the pc browser. Normally it takes maybe a minute, this time it was taking almost 15 and failed a couple times.Nothing was changed to allow Tablo to start working again. One second it gave the connection error and a second later it connected.
Since that day everything has been running perfectly smooth again without the need for VPN. The only thing that makes any sense is Tablo glitched and needed to be rebooted. This is why a login vs a need to pair devices would be beneficial. You could at least set the Tablo to be remotely rebooted using a smart plug and then to regain connection remotely, you wouldnt need to be there to pair devices.
