Hi all, I am setting up an Hyperledger Fabric network using docker-compose. I have some containers and some of them (orderers) need talk each others to elect a raft leader. When i see at the grpc logs i have this type of error:

[core]pickfirstBalancer: UpdateSubConnState: 0xc000496280, {TRANSIENT_FAILURE connection error: desc = "transport: Error while dialing dial tcp 172.18.0.3:8050: connect: connection refused"}

I tried to add the host names indicated in the compose file to the hosts file (i'm using ubuntu 20.04) but without success.

Can you help me with this issue?

This is my docker-compose yaml:

version: '2'

This sounds like it might be a more generic networking (docker config) problem than a gRPC issue. Are your containers able to reach each other using other operations (e.g. ping)?

Yes, it was a configuration problem. I solved it.

However, thanks for your reply.
