node.js - Error Running custom blockchain(hyperledger) application with security enabled -


i'm running blockchain application on local network setup using vagrant.
network (ca , vp ) running inside vagrant vm while application resides outside vagrant. when ran application security disabled, works fine. when tried security enabled, i'm getting following error:

what weird in logs, says no membership users found after filtering re deployed chaincode same enrollid , enrollpw i've mentioned in app.js blockchain js configuration. following details:

what "must supply username chaincode" mean. has faced similar issue while running security enabled on local network ?
update: so, changed enrillid user_type1_xxx , "no membership users found.." message doesn't come anymore. i'm getting connection refused error when user trying register.
