Handshake failed with fatal error SSL_ERROR_SSL

I'm following this tutorial https://hyperledger.github.io/composer/latest/tutorials/deploy-to-fabric-multi-org to deploy a composer blockchain business network to Hyperledger Fabric (multiple organizations)

I'm getting the following error however when trying to install the business network though:

I have checked that all the credentials in ~/.composer match up with the corresponding credentials in:

crypt-config/peerOrganizations/org1.blockaviation.com/peers/peer0.org1.blockaviation.com/tls/ca.crt
crypto-config/peerOrganizations/org2.blockaviation.com/peers/peer0.org2.blockaviation.com/tls/ca.crt

So I dont know why it is throwing an error if they do match up - Any help greatly appreciated...

Composer version: v0.19.1 Fabric V1.1.0

You have target name overides set for the peers under grpc options, and you have verify:false set for the CAs - so it does not look like any host naming problem.

If you look at the logs for the Orderer, Peers and CA you will see more detail of the error you will probably find an MSP mismatch.

If errors in the logs don't point you to the immediate problem I would suggest searching through all your docker compose yaml files, and crypto-config.yaml and configtx.yaml for example or example.com as it is likely that one has been missed in your replacement with blockaviation. (Remember to also check the script.sh file, and the 2 yaml files in the base folder)
