tvos 17.5.1 stalls out at 2 min of downloading and fails to verify

On 2x Apple TV HDs, I've had both units stall at 2 minutes of downloading. One completed download and update verification fails. I have verified internet connection is good and stable and have restarted both units. I'm more posting as I've read elsewhere of similar. I've never had TVOS issues before through all updates, so this is a first.
