I am trying to deploy a business network using command:

composer network start -c PeerAdmin@hlfv1 -n test-bna -V 0.0.1 -A admin -S adminpw

And it is failing with error:

Error trying to start business network. Error: Failed to connect to any peer event hubs. It is required that at least 1 event hub has been connected to receive the commit event.

On checking the composer logs, it says:

2018-11-08T13:30:59.190Z WARN :HLFConnection
:_connectToEventHubs() event hub localhost:7051 failed to connect: 12 UNIMPLEMENTED: unknown service protos.Deliver {}$ 2018-11-08T13:31:46.763Z WARN :HLFConnection
:_connectToEventHubs() event hub localhost:7051 failed to connect: 12 UNIMPLEMENTED: unknown service protos.Deliver {}$

Could someone please help with resolving this?

What version of Composer are you using, and what version of Fabric ? Are there any errors in the Peer log? – R Thatcher Nov 08 '18 at 14:41
There are no errors in Peer log. Composer version is 0.20.4 and fabric version is hlfv1 – Anand Nov 09 '18 at 15:20
For Composer v20.4 you need Fabric v1.2.1 – R Thatcher Nov 09 '18 at 16:26

Thank you. Looks like it was version mismatch. I updated the versions and now the command is successful. – Anand Nov 09 '18 at 16:45
I have this same issue my versions are composer v20.6 and fabric v1.2.1 But the command still does not work, any ideas? – Jay P Feb 23 '19 at 16:45
