Are you able to start the tethering again?
Are you working on Mac or windows?
I’m using Windows 7. Sometimes I have to reboot the whole system to reconnect. Yesterday, I was able to reconnect it by creating a new folder for the tether destination.

What is the tether destination?
Camera to USB port on laptop (Windows 7). In Lightroom, I select File>>Tethered Capture>>Start Tethered Capture. I make sure it is going to the correct folder. It works perfectly, until I export file(s) to a hard drive or flash drive. Then it says it is not connected.
I solved the problem by networking a second laptop (Ethernet crossover cable). I can then access the folder on the tethered laptop and burn them to the flash drive on the second laptop. It worked flawlessly.
