I've improved the error message a bit so that the next people to hit the issue at least know which communication has failed upfront:

Thanks Dave. The error message was not clear why it was failing.

For others, if you end up with the same issue, to fix the error, make sure the TLS arguments passed correctly. An example working instantiation command with TLS is:

peer chaincode instantiate -o orderer:7050 --tls --cafile /fabric/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n $CHAINCODE_NAME -v $CHAINCODE_VERSION -c '{"Args":["init", "a", "100", "b", "200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"

Thanks,
Suresh

As indicated at https://stackoverflow.com/questions/55394476/error-could-not-send-eof-on-instantiating-chaincode , EOF can be caused by TLS issues between client and orderer.
This issue is now resolved by fixing the instantiate command TLS settings.

Looks like the client failed to send the results to the ordering service node:
https://github.com/hyperledger/fabric/blob/release-1.4/peer/common/broadcastclient.go#L63
Not sure why grpc returned EOF upon send though...

I was getting timeout error earlier, but as I increased timeout values now I don’t see any timeout error . Current values of timeouts are: CORE_CHAINCODE_EXECUTETIMEOUT: 60000s and CORE_CHAINCODE_DEPLOYTIMEOUT: 60000s

On the client side I am getting this error for instantiation step: `Error: could not send: EOF`

Snippet is:

```
peer chaincode instantiate -o orderer:7050 — tls — cafile /fabric/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n $CHAINCODE_NAME -v $CHAINCODE_VERSION -c '{"Args":["init", "a", "100", "b", "200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"
