Hi Andy, Thanks for your post.
I just followed your steps, we had the .pem file already imported I used openssl and keytool to convert pem to store in keystore, following are the command i used. Nifi-Error.png <http://apache-nifi-developer-list.39713.n7.nabble.com/file/t911/Nifi-Error.png> SSLControllerService.png <http://apache-nifi-developer-list.39713.n7.nabble.com/file/t911/SSLControllerService.png> openssl x509 -inform der -in ca.pem -out ca.cdr /opt/app/java/jdk1.8.0_112/bin/keytool -import -alias ca -keystore cacerts -file ca.der I created a StandardSSLContextService and pointed the created keystore file location, when I tested in the nifi process I am getting java.lang.Runtimeexception, there is no further traces available in the logs also. I have attached the screen shots of the error and the configuration also. Please let me know what could be the reason.
