Wrong channel in Guide

Guys - recently my App channel 8.1 (zip 02132) from Boston Does not appear in the Guide. I did NO manual scan. Is it the device or the Guide picking up the wrong info since the other channels seem to be ok.

On your DVR web ui, try clicking the circle refresh icon under your hdhomerun

Doesn’t react.

Click the “xxx channels” link- does it show a logo next to channel 8.1

Yup. Works now. Any idea why it would have dropped on its own?
