vRA application services 6.2.0 failed to register to vRA 6.2.0 with error - [ERROR] 404 Not Found

Dear experts:

    Did anyone get this kind of error as below:

prompt (admin) > register-vcac-server --componentRegistryUrl https://vcac-appl-new-94-110/ --ssoAdministratorUsername administrator@vsphere.local

Please enter the password for SSO Administrator: ************

Registering vCAC server, this will take few moments..

[ERROR] 404 Not Found

    My testing version is as below:

    VMware-vCAC-Appliance-6.2.0.0-2330392

    ApplicationServices-6.2.0.0-2299597

    But when I tested the following version:

    VMware-vCAC-Appliance-6.0.1.1-1768531

    ApplicationDirector-6.0.1.0-1571033

    It works very well for registering from vAppD to vCAC.

   Any know issue is existing, or I missed anything, please advise!

   Best Regards

   Danny Lin
