Unable to connect CloudStack with vCenter — API Not Responding Despite Network OK #11246

Hi team,

I'm facing an issue integrating CloudStack with a vCenter 8.0.2 (build 22617221). Although all network checks pass, the API calls from CloudStack to vCenter are failing.

vCenter version: 8.0.2 (build 22617221)

CloudStack version: CloudStack 4.20.0.0

ping, telnet to port 443 from CloudStack server to vcenter working fine

vCenter web UI accessible

All core services are running (vpxd, vmware-vapi-endpoint, vsphere-ui, vmware-rhttpproxy)
