Getting issue with Zero cluster

HI… i am Sundar i am testing Dgraph cluster on my local kubernets I have 2 zero and 2 alpha
and i have 2 node kubernets cluster in each node 1 alpha and 1 zero are running.
If one node goes down the alpha is working fine but zero is connecting i am getting a error (“E0125 10:57:26.012874 17 groups.go:773] While sending membership update: rpc error: code = Unknown desc = Not Zero leader. Aborting proposal: member:<id:2 group_id:1 addr:“dgraph-alpha-1.dgraph-alpha.default.svc.cluster.local:7080” leader:true last_update:1611572246 >”)

(" Error while retrieving timestamps: rpc error: code = Unknown desc = Assigning IDs is only allowed on leader. with delay: 20ms. Will retry…")

can you help out for this issue thanks in advance.

The size of the quorum has to be an odd number. Set your cluster to 3 zeros and 3 alphas.
