As mentioned in this topic:
I’ve also been seeing this a lot recently, but I don’t use Google Drive.
It started a few versions ago (AppleTV version).
Before, I would see the error very, very rarely. For example, if the network actually went down.
Now, intermittently, I see if when the app resumes from background. The screensaver has kicked-in, and then dismissed. After using the task switcher to return to infuse.
My setup is wired gigabit ethernet to NAS drives. It seems uncorrelated with network usage, and I usually see it when playback isn’t currently happening.
Rarely an evening goes by without me seeing it more than once!
