thank you @Matt Clarke! Now it seems to be working, but the RPG throws another exception: Do I need to create a specific user and set the policy "retrieve data via site-to-site" in the Input Port of the nifi flow? ... View more

@Matt Clarke I used the command: ./bin/tls-toolkit.sh standalone -n '<ip address of the nifi server>' -C 'CN=<username>, OU=NIFI' -o './target' and followed the tutorial (but only one node instead of 2): https://bryanbende.com/development/2016/08/17/apache-nifi-1-0-0-authorization-and-multi-tenancy Do I need another command/argument to generate the keystore and truststore?
