VCSA 6.5 adding to domain

This is a new VCSA 6.5 adn the domain is almost new.

When trying to add the VCSA to Active Directory it is reporting:

Idm client exception: Error trying to join AD, error code [41887], user [administrator@domain], domain [domain.com], orgUnit [Computers]

Have not found a message that will help me with this error.

Tried to do it from the cli using SSH but it failed also.
