Streaming connection lost

I keep getting a “connection lost” error that says streaming to the HDHomerun has been lost. The error code is E0F. I’m not even watching a HDHomeRun channel when this happens but rather an M3U source. All the log says is that it closed the connection to the stream.
I also keep getting something in the log sayings it’s sharing the stream, even though that’s the only client playing tv. What is that about? Thanks!
