我正在尝试使用 Hyperledger Explorer 设置 Hyperledger Fabric 网络。我用 ubuntu 操作系统在数字海洋云上启动了一个虚拟机。从那里，我启动了 3 个排序节点和 2 个对等节点。结果总共有5个节点。（我正在使用 RAFT 设置）。
但是，在尝试启动 hyperledger fabric explorer docker-container images 时遇到如下错误。
错误：

我尝试过的解决方案
1.更改tlscs证书路径
如 Hyperledger Fabric 2.0.1 中所述：错误：在 Discoverer-name 的截止日期之前无法连接：
问题很可能是由于路径错误。但问题仍然存在。
2. 将环境变量 DISCOVERY_AS_LOCALHOST=true 更改为 false
他们中的一些人提到这将解决问题。但我似乎无法以这种方式解决它。
3. 尝试使用 hyperledger fabric 2.0 测试网络
我尝试使用织物样本测试网络运行，它运行得非常好。
4. docker exec -it sh 到 explorer.mynetwork.com 以 ping 对等点
ping 可以正常运行。
/opt/explorer # ping peer1.acme.com:7051

我现在正在为这个错误苦苦挣扎几天。希望有人可以帮助我找出问题所在。非常感谢你。
