I am also facing similar issue. I have installed the configured the Commvault Splunk plugin available at: https://splunkbase.splunk.com/app/5718/ and I am trying to get respective data from Commvalut version-11.24.48.
I have checked the permissions for the user(not a service account) of Commcell it is same as per your shared screenshot still no luck.
Also I am using the port 81 in the format <webserver_url>:<IIS port number> for setting up the Commcell page. This port is open from splunk to commvault but is not open from commvault to splunk
