CMT (channel 57) not available on Contour box

For a second evening, we’ll have to spend the 10 minutes or so rebooting our Contour box (by disconnecting and reconnecting the power source) to get this channel.  We get a message that the “problem is on our end, this channel is not currently available.”  The channel is available on the Contour app on my iPad and on the mini box in another room.  

Anyone else having this issue?  Is there a more permanent solution?
