VCDA – Unable to connect to vCenter

VCDA
  • TL/DR – This post lists the investigation and troubleshooting steps taken, but no fix.  No tech support since this is a lab.
  • VCDA 4.7.0.8400987-96215f032c in a VC to VC setup (no VCD) using vCenter 7.0.3 and ESXi 7.0.3, 20328353.  VCDA was born on version 4.4
  • Site A has an outgoing V2V Protection to Site B.
    Both sites VCDA’s report an banner error message for VM in scope – Unable to connect to vCenter ‘d5dd61d8-462d-44c1-9cd2-3e7b5b4f0362’.
  • New Outgoing Protection show the same error.
  • The vCenter cert did not expire (on both sites)
  • The guest VM in scope of replication is online.
  • VCSA on both site Setting and Peer Site do not report any issues. System health all green.
  • VCDA where the VM is resides, Settings / Service endpoints / Lookup Service address / Edit
  • Re-entered the VCDA service account used for the VC.
    Did not resolve.
  • Reboot the VCDA VM. Did not resolve.
  • Repeated the same 2 step on the destination site VCDA. Did not resolve.
  • Replicator Services administration
  • Repaired the same VCDA.
  • Reading https://knowledge.broadcom.com/external/article/315168/unable-to-connect-to-vcenter-error-when.html
    “This issue occurs on the destination site when the instance UUID of a resource vCenter Server in Cloud Director has changed, but Cloud Director is not aware of the vCenter UUID change or Cloud Director has an incorrect value saved for the vCenter UUID.”
  • Does not apply since there were not VC change to trigger a new UUID.
  • /opt/vmware/h4/cloud/log does not have any log files.
  • grep instanceUuid /etc/vmware-vpx/instance.cfg

    shows Sita A’s vCenter matches the VCDA error ID>
