I had this error when creating a reeencrypt secure route on Openshift,
spec.tls.certificate: Invalid value: "redacted certificate data": error verifying certificate: x509: certificate signed by unknown authority reason: ExtendedValidationFailed
this is the oc command that im using,
oc create route reeencrypt my-https --service my-gateway-https --key private.key --cert server.pem --cacert cacert.pem -n my-project
This error is due to im using an incorrect certificate for reencrypting. Using certificate decoder shows whats wrong with my certificate,

The correct certificate should show this,

Regenerating my certificate fix this issue.
