Cause

This probe fails if one of the below conditions are met:

• If there is a mismatch of admin-certificates in node-0 (admin server) and node-x (all other servers).
• If the permissions are incorrect for admin-cert.pem.

Resolution

Please follow below instructions to fix the probe error :
The ‘admin-cert’ is expected to be the same as the ‘admin server’ across the entire environment.

1. Copy the ‘admin-cert.pem’ certificate from the admin server (/etc/pki/nw/peer/admin-cert.pem) to all the node-x servers and and paste it into the same directory location /etc/pki/nw/peer/ where ‘admin-cert.pem’ is not matching.

   # cd /etc/pki/nw/peer/
   # chown netwitness:nwpki admin-cert.pem
   
3. The file permissions will look like the following:
