Question

Hyperledger peers with TLS in kubernetes cluster constantly keep throwing TLS handshake errors

12/6/2019

Below are the peer logs:

2019-12-06 07:00:31.121 UTC [core.comm] ServerHandshake -> ERRO fa975 TLS handshake failed with error EOF server=ChaincodeServer remoteaddress=192.168.131.215:25731
2019-12-06 07:00:31.215 UTC [core.comm] ServerHandshake -> ERRO fa976 TLS handshake failed with error EOF server=ChaincodeServer remoteaddress=192.168.131.215:20784
2019-12-06 07:00:31.301 UTC [core.comm] ServerHandshake -> ERRO fa977 TLS handshake failed with error EOF server=PeerServer remoteaddress=192.168.131.215:8059
2019-12-06 07:00:31.512 UTC [core.comm] ServerHandshake -> ERRO fa978 TLS handshake failed with error EOF server=ChaincodeServer remoteaddress=192.168.163.185:46359
2019-12-06 07:00:31.768 UTC [core.comm] ServerHandshake -> ERRO fa979 TLS handshake failed with error EOF server=PeerServer remoteaddress=192.168.131.215:34603

Everything is working fine. We are able to do transactions on the chaincode. Can anyone please help us on this issue?

Peer and orderer identity is created in the startup scripts and stored locally in the container.

This happens when you are using wrong certificates.

What are the two parties? 2 peers or 1 peer 1 orderer? Or maybe the client?

The two parties must have valid TLS certificates, here you are using some wrong ones.
