Remote tuner unavailable

Every once in a while, I get a remote tuner unavailable on my apple tv. It seems random and not channel specific. I go and click on a channel and it says it's unavailable. I click on another channel and it works. If I close the app and relaunch the app the channel seems to work again. Any ideas?

Please submit diagnostics next time it happens

Thanks. Looks like server side error, so check the DVR Log tab around the time it failed to see if there is any error
