Forbidden Error when open NIFI UI

[#1]

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:

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

Hi Ckumar, recently I can not open the UI because the error of 403 when I check the nifi-request.log file also. I think all error come from same reason.
