Multi Cluster Replication Config

Hello Team, We are trying to setup multi cluster replication for our Temporal Server hosted on EKS.

In helm Charts
The config for us east 1 looks like:
clusterMetadata:
enableGlobalNamespace: true
replicationConsumer:
type: rpc
failoverVersionIncrement: 10
masterClusterName: useast1
currentClusterName: useast1
clusterInformation:
useast1:
enabled: true
initialFailoverVersion: 1
rpcAddress: “abc-us-east-1.xxx.com:443

and

 clusterMetadata:
  enableGlobalNamespace: true
  replicationConsumer:
    type: rpc
  failoverVersionIncrement: 10
  masterClusterName: uswest2
  currentClusterName: uswest2
  clusterInformation:
    uswest2:
      enabled: true
      initialFailoverVersion: 1
      rpcAddress: "abc-us-west-2.xxx.com:443"

The upsert call to the useast1 server
temporal operator cluster upsert --env qa --frontend-address=abc-us-west-2.xxx.com:443 --tls-disable-host-verification=true

We are getting error Context Deadline Exceeded.

Can someone share the next steps after that
