Error downloading best block: API returned incorrect number of block summaries: n=1

[placer14]

I noticed that a particular block caused two instances of hindsight to miss a block as a result of this error: Error downloading best block: API returned incorrect number of block summaries: n=1

It appears we perform an HTTP request of the full block data from insight when a new block is detected via the websocket. If this request fails for any reason, we simply do not report the block to anything. Wondering if there's a better way to solve this? Maybe attempt to retry a few times?
