The operation makes use of the server that's not currently assigned to a server pool and the requesting user is not a cluster administrator. Because of that use of the server cannot be authorized at the moment.
Either request a cluster administrator to perform the operation for you or wait until the server has joined the cluster and is assigned to a pool to which you have an x-permission.
