$ oc get --raw=/.well-known/oauth-authorization-server | jq -r .issuer
https://oauth-clusters-hypershift-ci-283235.apps.xxxx.com:443

2. Panics when anonymously curl'ed:
$ curl -k "https://oauth-clusters-hypershift-ci-283235.apps.xxxx.com:443/oauth/authorize?response_type=token&client_id=openshift-challenging-client"
This request caused apiserver to panic. Look in the logs for details.
