Requests denied because of security concerns.

For TCP this is because of a matched tcp-request content rule.
For HTTP this is because of a matched http-request or tarpit rule.

haproxy.stat.request.queued.current

early termination from the client, before the request has been sent
read error from the client
client timeout
client closed connection
various bad requests from the client.
request was tarpitted.

haproxy.stat.request.redispatched

Number of times a request was redispatched to another server. For servers, this field reports the number of times the server was switched away from.

haproxy.stat.request.connection.errors

type: long

Number of requests that encountered an error trying to connect to a server. For backends, this field reports the sum of the stat for all backend servers, plus any connection errors not associated with a particular server (such as the backend having no active servers).
