So I've re-read this entire thread a couple times now and one thing stood out to me. It was pointed out that the cables or connectors between the Hopper and the dish could be the cause. That reminded me that before I had this problem, I accidently yanked the crimp connector off the end of one of the coax runs. This is the run that goes between the Hopper to the Solo Hub. At the time I didn't have any new connectors so I just shoved the same connector back on and used a smaller setting on my crimp tool to get it tight. It's been working all this time (so I thought), but that could be the cause of my issue. I have new crimp connectors now so I just cut that end off and put a new connector on it the correct way. Everything is up and running again now so time will tell if that really was the cause of the issue.
