juju não pode criar uma nova máquina no Azure

Question

Eu estou jogando com juju no Azure e consegui implantar (juju-gui, mysql, tomcat7). e eu também destruí alguns serviços.

Devo mencionar que também habilitei a alta disponibilidade do juju usando o comando

juju ensure-availability

Quando tentei implantar o encanto HaProxy, ele fica preso dizendo

agent-state-info: 'cannot get machine 9: EOF'

Eu não encontrei este googling ou em documentações de juju.

Por gentileza, o que essa mensagem de erro significa? Como evitar isso da próxima vez? cometi um erro com as configurações? Como resolver isso? fazendo juju resolved haproxy/0 me dá ERROR unit "haproxy/0" is not in an error state devo destruir o charme? Obrigado

Aqui está o meu resultado juju status haproxy/0

C:\Program Files (x86)\Juju>juju status haproxy/0
environment: azure
machines:
  "9":
    agent-state-info: 'cannot get machine 9: EOF'

      - tomcat7
    units:
      haproxy/0:
        agent-state: allocating
        machine: "9"

e aqui está o status completo (é longo; p):
