GlobalDNS issues with Rancher 2.x

Hi, i am using rancher 2.x with cloudflare for global dns.

  • Rancher with cluster A and cluster B
  • Deployed my application to cluster A and cluster B with rancher fleet
  • Create annotation with = value hostname
  • Created dns entry = value hostname
  • Rancher generate subdomain with A record to cluster A and cluster B
  • Success access with subdomain

But, if the cluster A down, cluster B doesn’t access from subdomain. So load balance not working to multiple cluster.

Please help me, how to fix this?
