Host license edition is not allowed.
Edition of the license installed on the host is not compatible with the vCenter license edition. For example, vCenter Server uses the vCenter Server Standard license, and the host connected to this vCenter Server uses the vSphere Essentials license.
Install a compatible license on the host. For example, if vCenter Server uses the vCenter Server Standard license, install the vCenter Server Standard license on the host, too.
Refer to the VMware Online Documentation for more information on vCenter event messages and possible solutions.
