Hello! I am having issues getting NiFi Registry to work properly.
I have NiFi and NiFi Registry running, both configured to use SSL, both using the same keystore.jks and truststore.jks files, and both with user accounts mapped to PKI certificate FQDNs. I have no issue logging into the interfaces for either NiFi or NiFi Registry. I have added the NiFi registry URL in NiFi under nifi settings -> Registry Clients. I have created a bucket in nifi registry. It is set to be publicly visible and has a policy created that gives the user group (which I created in nifi registry and has all users in it) all permission options. In Nifi, I have a user group created with all users in it that have maximum permissions for all options in Nifi and on the particular nifi flow we're working on. The issue I have is: 1.) I log in to NiFi, right-click a process group (doesn't seem to matter which one) and click Version -> Start version control. 2.) The Save Flow Version wizard pops up, automatically populated with the registry name and the bucket name I created in nifi-registry. I enter random characters in the 3 empty fields and click Save. 3.) Error message appears: "Failed to register flow with Flow Registry due to Error creating flow: Untrusted proxy [*<NIFI SSL CERTIFICATE FQDN>*] for write operation. Contact the system administrator." In the nifi-registry-app.log, I see this message: 2020-03-05 18:16:11,272 INFO [NiFi Registry Web Server-17] o.a.n.r.w.m.AccessDeniedExceptionMapper identity[*<MY CERTIFICATE FQDN>*], groups[*<MY NIFI GROUP>]* does not have permission to access the requested resource. Untrusted proxy [*<NIFI SSL CERTIFICATE FQDN>*] for write operation. Returning Forbidden response. However, my account has every permission available in both Nifi and Nifi-registry. Any idea where to start?
