Explanation
The key difference between configuring Hybrid Linked Mode from the Cloud Gateway Appliance and the VMware vSphere Client is that the Cloud Gateway Appliance reveals the on-premises inventory while the VMware vSphere Client does not reveal the on-premises inventory. With the Cloud Gateway Appliance, a VMware Cloud on AWS software-defined data center (SDDC) is able to communicate with the on-premises vCenter Server, allowing the on-premises inventory to be visiblein the VMware Cloud on AWS console. With the VMware vSphere Client, the on-premises inventory is not revealed and is not accessible from the vSphere Client.

Explanation
The problem could be that the new password is not synchronized with the password that is displayed for the Default vCenter user account. The administrator must make sure that the same password is used in both the vSphere Client and the VMware Cloud console in order for the user to access the account. Changing the password in one place does not automatically change it in the other, so this must be done manually.
