Maybe a Eucharistic Miracle happened in Connecticut, and maybe it didn’t (a multiplication miracle would be impossible to confirm without some very detailed video). However, keep in mind that in the past, Eucharistic miracles often happen where there is a lack of Faith- not an abundance of it.
And the Bible states:
11 Then the Pharisees came and began to argue with Jesus, testing Him by demanding from Him a sign from heaven.
12 Jesus sighed deeply in His spirit and said, “Why does this generation demand a sign? Truly I tell you, no sign will be given to this generation.” 1Mark 8:11-12
