The League One high-fliers were beaten 2-1 despite taking a second-minute lead through Jack Taylor.
Goals from Connor Hall and Lewis Baines put the National League North strugglers through to the next round and dreaming of a date with Premier League giants.
Ferguson said: “Shocks like this are what the FA Cup is about.
“These games are televised because of the chance of an upset and they got exactly what they came here for.
“I’ve got no complaints as we were second-best all over the pitch and we should have lost by more in all truth.
“Sometimes in a cup match you can lose to a deflection or have complete domination, but the other team score from their only two chances.
“But that wasn’t the case today and I have to dig a bit deeper to get to the bottom of a performance that was completely unacceptable for this football club.
