The Ravens are thirteenth in the table after back to back losses, writes Tom Feaheny.
They looked set to draw their match at the weekend before James Norwood struck with just 30 seconds of the game left to play.
"We are going to have to bounce back, Maidstone are flying at the moment, we will work hard moving into that game and look to find positives from this match," said Smith to the club's website.
"It shows how far we have come that we have faced the biggest team in the league and are disappointed with a late loss, but it still hurts."
"It was very tough, we didn't deserve to win but neither did they, we have a lapse right at the end, the 0-0 would have been a fair scoreline, we didn't have many chances but we were resolute at the back."
