Environment

• VCF Operations 9.x

Cause

This issue occurs when the Fleet Manager appliance has been manually deleted, powered off, or rendered unreachable

Resolution

To resolve this issue, you must power on the Fleet Manager, if it is deleted, restore the Fleet Manager appliance and ensure network connectivity between the Fleet Manager and VCF Operations.

1.  Restore the Fleet Manager VM from a known good backup.
2.  Ensure the VM is powered on and all VCF services are started.
3.  Perform a connectivity check in both directions using curl to ensure port 443 is open
4. Check the connectivity From Fleet Manager to VCF Operations and vice-versa
5. Run the below command from Fleet Manager 
   

   curl -v telnet://<VCF_OPS_FQDN>:443

6. Run the below command from VCF Ops 

   curl -v telnet://<FLEET_MANAGER_FQDN>:443

7. Retry Deployment: Once connectivity is confirmed, navigate to the VCF Operations UI and retry the failed Component import task from the Build > Lifecycle > Tasks view.
