Estou iniciando uma rede, que terá 3 pares e um pedido. Eu tenho 4 máquinas virtuais diferentes, uma para cada nó.

Sigo o manual de introdução do Hyperledger Fabric. Eu executo todas as etapas sem nenhum problema. No entanto, após executar o seguinte comandopeer channel join -b channeldemo.block, Começo a receber alguns erros. Parece-me que o comando anterior é gerado bem, porque recebo os seguintes logs:

2017-06-27 08:26:23.247 UTC [channelCmd] executeJoin -> INFO 00a Peer joined the channel!
2017-06-27 08:26:23.247 UTC [main] main -> INFO 00b Exiting.....

Mas, depois disso, recebo os seguintes logs no par:

peer0.proveedor.com    | 2017-06-27 08:26:29.241 UTC [deliveryClient] StartDeliverForChannel -> DEBU 2d8 This peer will pass blocks from orderer service to other peers for channel canaltraza

No entanto, se eu iniciar a rede no meu host local, não recebo nenhum log de erros. Depois que um par entra no canal, recebo as seguintes mensagens (existem mensagens do par e do ordenador):
