Thanks for looking into it Jared.
This is quite a mystery for me. I'm running SGP and PHD2 on a headless PC stick at my scope, so no possibility of a critter or other nefarious users interrupting the session. Also, I looked into the logs to make sure that I didn't login with my phone while asleep and abort it. It shows a VNC session login at 2:43am from my phone's IP and that session is terminated at 2:46am. The next login occurs at 3:49 when I'm checking on things before closing down for the night.
