我也遇到了同样的问题。我正在处理中。 - Manoj Kumar

Answer 1

您能否尝试将对等方的"url"和"eventUrl"更改为以下格式：

"url": "grpcs://peer0.org1.example.com:7051"

我正在使用Docker实例来运行区块链浏览器，这种格式对我很有效。

尝试了您的建议，但是没有起作用。在将localhost更改为peer0.org1.example.com后，连接被拒绝。 - Akanksha Tiwari

Answer 2

我在 blockchain-explorer/app 下的 explorerconfig.json 中更改了同步设置。

"sync": {
"type": "host",
"platform": "fabric",
"blocksSyncTime": "3"

}

错误已经消失。

Answer 3

在我的情况下，我缺少了最后一行（CORE_PEER_GOSSIP_EXTERNALENDPOINT）。

peer0.org1.example.com:
container_name: peer0.org1.example.com
image: hyperledger/fabric-peer
environment:
  - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
  - CORE_PEER_ID=peer0.org1.example.com
  - CORE_LOGGING_PEER=info
  - CORE_CHAINCODE_LOGGING_LEVEL=info
  - CORE_PEER_LOCALMSPID=Org1MSP
  - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/peer/
  - CORE_PEER_ADDRESS=peer0.org1.example.com:7051
  - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org1.example.com:7051

在相应的docker-compose.yml文件中描述网络。 如果没有这行，似乎peer只能在组织内部可见。 您还需要运行./generate.sh和./start.sh来启动您的网络。 希望对您有所帮助。

Answer 4

您需要找到正在运行的同行和排序器的IP和端口，并在config.json中进行更改。 您可以使用docker ps确保容器正在运行，并查看与每个容器相关的端口。
此外，还要查看this link关于Explorer的信息。该链接显示了更改config.json并运行explorer所需的步骤。
