Erro ao conectar ao mongoDB

Boa noite. Estou com um problema o servidor inicializa normalmente e até o momento em que criamos os models, tudo estava funcionando.

Após criar os models comecei a receber o seguinte erro:

com.mongodb.MongoSocketOpenException: Exception opening socket

OBS: Inicializei o mongo da seguinte forma:

mongod --dbpath C:\Users\jorge\Documents\javamongo\db

O que pode estar errado ?
