Today I have faced the strange issue, I tried to add new host to vcenter but unable to add to check the VCenter services I tried to login to Vcenter appliance Management UI but unable to login.

I tried to reset the Vcenter Appliance root passowrd but didn’t work. After troubleshoting I found the solution. Applmgmt Services was not running which was not allowing me login to management Console.

So Check the services status from Shell , open VCenter Appliance Console / SSH.

Access à Shell

#service-control –status

#service-control –start applmgmt

Once Services started , I am able to login to console & able to add ESXi host to VCenter.
