Hi,

I got the following error when running the command:

grpc_cli ls xx.xx.xx.xx:5678

Received an error when querying services endpoint.

ServerReflectionInfo rpc failed. Error code: 14, message: failed to connect to all addresses, debug info: {"created":"@1560812406.728533687","description":"Failed to pick subchannel","file":"third_party/grpc/src/core/ext/filters/client_channel/client_channel.cc","file_line":3378,"referenced_errors":[{"created":"@1560812406.728372027","description":"failed to connect to all addresses","file":"third_party/grpc/src/core/ext/filters/client_channel/lb_policy/pick_first/pick_first.cc","file_line":453,"grpc_status":14}]}

I followed the instructions at https://github.com/grpc/grpc/blob/master/doc/server_reflection_tutorial.md to enable the reflection service.

Can anyone tell me how to debug this issue?

Thanks,

Jun
