Hi
Thanks for the days and help, but I managed to solve the problem.
After a few attempts to restore trust between the cluster nodes, with LB and discover by vRLCM, both without success.
I shut down all VMs, took a snapshot, preparing to redo the vIDM by hand (unregistering and registering a new one via API - https://docs.vmware.com/en/VMware-vRealize-Suite-Lifecycle-Manager/2018/ com.vmware.vrsuite.lcm_api_21.doc / GUID-21559F8F-C6BD-47B6-A79B-B5FF9F716941.html).
I turned on vRLCM and then turned on vIDM via LifeCycle, when I realized that the management, which was not happening before, worked, from then on I did the whole process of product discovery, re-trust, etc ...
I consulted the NSX, saw that all the nodes appeared as up, did some validations in the logs and realized that the cluster was UP again.
Thanks.
