How to monitor remote vCenter and ESXI using minion

Problem:
How can I monitor remote vcenter and esxi hosts using minion server?
OpenNMS server does not have access to the remote network.
If I add the esxi host as a new node of the remote site, it also causes login error when daily scan is executed: “Remote access for ESXi local user account has been locked for 900 seconds after X failed login attempts”

Expected outcome:
Monitor vcenter and esxi hosts using remote minion server.
No login errors expected.

OpenNMS version:
24.1

thanks in advance for the support
