Hello Matt, I have same issue connecting minifi to the Nifi using ssl, Checked all your recommendation, but couldn't identify the issue. - The configure "transport protocol" is set to RAW. Was this method enabled on the target NiFi? : it is HTTP - Is port 8011 the configured port used for the NiFi URL on target NiFi? : yes ( port 9091) - Are the permissions and ownership on the keystore and truststore files on your MiNiFi set correctly? ( Yes ) - Do you see any authentication or authorization log lines coming from this MiNiFi host in the nifi-user.log on the target NiFi? ( No ) - Does the content of both truststore.jks files (MiNiFi and NiFi) contain identical entries? ( Yes ) Error message : ( Minifi Log) 2018-02-21 11:23:23,306 ERROR [Remote Process Group 097540fc-19d1-355c-b129-71ce900782e7 Thread-1] org.apache.nifi.engine.FlowEngine A flow controller task executi
