<p>I have been trying to deploy a hyperledger fabric model with 3 CAs 1 orderer and 2 peer nodes. I am able to create the channel with OSADMIN command of fabric but when I try to join the channel with peer node, I get Error: <code>error getting endorser client for channel: endorser client failed to connect to peer-govt:7051: failed to create new connection: context......</code> .</p>
<p>Here are the logs from terminal (local host machine):</p>

<p>One thing to note down here is I am using Kubernetes and service CLUSTER_IP for all the PODS.</p>
<p>here are logs from one of the PEER POD (same for other)</p>

</code></pre>
<p>To overcome this issue, I tried disabling the TLS by setting <code>CORE_PEER_TLS_ENABLED</code> to <code>FALSE</code></p>
<p>then the proposal gets submitted but the orderer POD throws the same error of <code>TLS handshake failed.........</code></p>
<p>Here are the commands I am using to join the channel from cli pod:</p>
<p><code>kubectl -n hyperledger -it exec $CLI_POD -- sh -c &quot;export FABRIC_CFG_PATH=/etc/hyperledger/clipod/config &amp;&amp; export CORE_PEER_LOCALMSPID=GeneralMSP &amp;&amp; export CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/clipod/organizations/peerOrganizations/general.example.com/peers/peer0.general.example.com/tls/ca.crt &amp;&amp; export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/clipod/organizations/peerOrganizations/general.example.com/users/Admin@general.example.com/msp &amp;&amp; export CORE_PEER_ADDRESS=peer-general:9051 &amp;&amp; peer channel join -b /etc/hyperledger/clipod/channel-artifacts/$CHANNEL_NAME.block -o orderer:7050 --tls --cafile /etc/hyperledger/clipod/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem&quot;</code></p>
<p>I am stuck on this problem, any help will be appreciated.
Thank you</p>

<p>I have fixed it. The issue I was facing was because of not setting the <code>CORE_PEER_TLS_ENABLED = true</code> for CLI pod.</p>
<p>One thing I have got learn from this whole model, whenever you see TLS issue, first to check for would be checking <code>CORE_PEER_TLS_ENABLED</code> variable. Make sure you have set it for all the pods or containers you are trying to interact with. The case can be false(for no TLS) or true(for using TLS) depending on your deployment.
Other things to keep in mind is using the correct variables of fabric including <code>FABRIC_CFG_PATH</code>, <code>CORE_PEER_LOCALMSPID</code>, <code>CORE_PEER_TLS_ROOTCERT_FILE</code>, <code>CORE_PEER_MSPCONFIGPATH</code> and some others depending on your command.</p>
