Forbidden Error when open NIFI UI

Question

I had an authorization error after running successfully NiFi service on the Cloudera Private Cloud Base Cluster. Here is the error log in nifi-user.log file:

2024-08-07 17:57:56,775 INFO [main] o.a.n.a.FileAccessPolicyProvider Authorizations file loaded at Wed Aug 07 17:57:56 ICT 2024

Here are all the services I am using:

I am using Java 11, I changed the NiFi directory from /var/lib/nifi, /var/log/nifi to /home/lib/nifi, /home/log/nifi because of the free space problem.

Does anyone know how to fix this? Thanks

From the logs snipped, it appears that the NiFi node does not have all the permissions, to get more clarity it would be nice if you could add the error you see in NiFi UI related to permissions.

Thank you
