However, Juan Barrera's goal 20 minutes into the second half secured a place for Nicaragua, who leapfrogged Montserrat on goal difference in the 34-team qualifying table of Confederation of North, Central American and Caribbean Association Football nations.
The top 10 teams qualified for the Gold Cup finals, among them Guyana and Bermuda, who will take part for the first time.
Group winners Haiti will be joined by Canada, Martinique, Curacao, Cuba, Jamaica and El Salvador.
Having qualified for the final round of the CONCACAF World Cup qualifiers last year, Costa Rica, Honduras, Mexico, Panama, Trinidad and Tobago, and the United States were handed automatic spots in the finals spot.
The biennial Gold Cup will take place in the United States, Costa Rica and an as yet undecided Caribbean country, with the kick off scheduled for June 15 and the final set for Chicago on July 7.
