Após o docker estar ativo, o host local se recusou a conectar

Question

Eu trabalhei com o superconjunto, e decidi rodar este link

Agora eu verifico o docker

sudo docker ps
CONTAINER ID        IMAGE                                      COMMAND                  CREATED             STATUS              PORTS                      NAMES

Mas não consigo me conectar ao superconjunto

This site can’t be reached
localhost refused to connect.

Por quê?
