vCenter SDK API connectivity problem for Openshift 4 installation: failed to create vSphere session: error setting up new vSphere SOAP client.

Solution Verified - Updated -

Issue

  • Need to determine why master nodes can't contact the vCenter through vCenter SDK endpoint https://vcenterdomain/sdk via port 443/TCP, which would be preventing the machine-api from creating new workers and holding up the entire installation.
  • The installation is not progressing due to some cluster-operators still degraded (ingress and all the operators depending on ingress such as auth), and workers not being deployed.

Environment

  • Red Hat Openshift Container Platform 4.x [RHOCP]
  • VMWare vCenter.
