Erro ao conectar o MySQL no Data Studio

Olá, pessoal! Tudo bem?

Preciso de ajuda. Estava na Aula 3 e fiz todas as configurações conforme as etapas. Adicionei os IPS do Data studio ao Google Cloud. Reiniciei e os ips apareceram, porém quando tento conectar no Data Studio aparece a mensagem de erro.

No cloud shell usei o comando

gcloud sql instances patch mysqldatastudio001 --assign-ip
gcloud sql instances describe mysqldatastudio001
gcloud sql instances patch mysqldatastudio001 --authorized-networks=64.18.0.0/20,64.233.160.0/19,66.102.0.0/20,66.249.80.0/20,72.14.192.0/18,74.125.0.0/16,108.177.8.0/21,142.251.74.0/23,173.194.0.0/16,207.126.144.0/20,209.85.128.0/17,216.58.192.0/19,216.239.32.0/19,191.183.110.162
gcloud sql instances describe mysqldatastudio001

E obtive as seguintes "autorizações" quando rodei o ultimo comando "describe"

ipConfiguration:

    - kind: sql#aclEntry
