Issue

• I am trying to upgrade my OpenShift Container Platform cluster from 3.7 to 3.9, and my installation fails at TASK openshift_web_console.

  TASK [openshift_web_console : Report console errors] *************************************************************************************************
  fatal: [master.example.com]: FAILED! => {"changed": false, "failed": true, "msg": "Console install failed."}
      to retry, use: --limit @/usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/upgrades/v3_9/upgrade.retry
  

• The TASK debug message is Error: unable to load server certificate: open /path/tls.crt: permission denied.
