During the auto deployment installation of additional NSX node using User Interface (UI), the NSX Node displays a status of "Waiting to Register VM" indefinitely.
Issues could be differet and must be checked case by case.
Workaround is do delete the node with issues over API.
First check all your deployments and grab vm_id.
Delete the node using next command:
https://10.3.60.179/api/v1/cluster/nodes/deployments/86f643e9-e722-451b-be68-9a9f08d0b5b7?action=delete
Bonus:
Issue with the deloyment in my case was laydown in NFS storage. Simly moving the delpoyment VM target to anither type of storage, solved issue.
