Apple TV - Can't continue playback because the server is not responding

Here’s some additional information I found. Via Reddit, I saw this thread:

I changed my DB cache size from 40mb to 2000mb and started a series of local streams from ATV, Xbox, iOS and Safari browser. I also have 3 remote users with ATVs running content. There has not been a single stoppage yet. I want to wait until tomorrow, or maybe even later in the week to further verify this has remediated my issue, but things seem to be operating normally now. I don’t understand how this might have solved the problem, but I’m marking this now for future reference. I’ll update later today, or later this week, with further findings.
