Build and run a Hyperledger Fabric network using the Raft consensus protocol. Deploy a five-node ordering service, submit transactions via the Fabcar UI, and test the network by stopping some of the ordering nodes.
first thanks for your awesome repo and videos, and other cool stuff posted, I learn a lot with it
I have a problem in my hlf raft network, and try with your repo and seems the same problem occurs,
I don't know if the problem is because of my limited knowledge about raft, it seems that we need first ordeder, and this don't make sense to me
let me explain the problem
if I stop any ordeder like orderer2, orderer3, orderer4 and orderer5, even two at the same time,
everything works as expected, same on my production network,
but when I stop first orderer network stops, and never responds, until I start orderer again and wait

stop ordeder
$ docker container stop orderer.example.com

we can see that network always try to connect to ordeder and fails
this only occur in both cases it I crash first ordeder/ordeder1,
if this is normal, the network will not be resillent,
it depends that ordeder/ordeder1 to be online, and if fail everything fails too
and sorry to ask I try google but I can't find answear for the problem
