Hi David, This typically means one of two things:
1. that the DN of the (client) certificate does not match the user in the receiving NiFi instance *exactly*. Inspect the logs (I think it’s nifi-user.log) to find the DN that the sending NiFi is providing and edit the username in the receiving NiFi instance. 2. The user is correct but does not have permissions to send data to the input port. Each input port needs these permissions set separately. Right-click on it and click “manage access policies”. In the dropdown box select “receive site-to-site data” and add the user or group that should be allowed to send data to this port. Hope this helps you find the issue.

I have gotten PKIX errors and Forbidden, but I am getting an Unauthorized message: [cid:image001.png@01DAC86E.8FE52D90] What is this telling me? Where is the problem in the permission chain? -- David
