I get a warning in Geth that I was not able to find any information on:

Checkpoint challenge timed out, dropping

What does this mean?

In geth's code you'll find the snippet bellow https://github.com/ethereum/go-ethereum/blob/master/eth/handler.go

// Start a timer to disconnect if the peer doesn't reply in time
        p.syncDrop = time.AfterFunc(syncChallengeTimeout, func() {
            p.Log().Warn("Checkpoint challenge timed out, dropping", "addr", p.RemoteAddr(), "type", p.Name())
            pm.removePeer(p.id)
        })

The comment explain what the log message means
