Symptoms

   An error occurred during registration. Please try to register the Management Server again

Cause

Two-factor authentication is not yet supported by online management server activation mechanism.

This feature will be implemented in future versions or the product.

Solution

There are two possible workarounds in this case:

• Use offline activation method (Activation through file): please refer to the page Activating management server > To register an offline management server. Offline activation is not affected by two-factor authentication.
