I had a working HCX setup in my lab and I was doing some modification in my setup and tried chopping off my interconnect networking configuration in HCX Cloud side. Deletion of interconnect configuration was failing for me with below error
Let me first explain how I landed in this situation.
I was deleting the interconnect appliances from my on-prem to show demo to my peers on how the interconnects are deployed via HCX plugin in vSphere webclient. During the demo I did not noticed that site pairing between my on-prem HCX and cloud side HCX was broken (due to vCenter upgrade in cloud side, cert mismatch issue occurred).
