https ssl test

Hello,

I somehow fail to understand how https tests are supposed to work.
This works fine for me:

---
check host self with address localhost
  if failed port 443 protocol https and certificate valid > 30 days then
  alert
---


However, this doesn't:
---
check host self with address localhost
  if failed port 443 protocol https and certificate valid > 30 days with
  ssl options {verify: enable} then alert
---

All I get is
---
failed protocol test [HTTP] at [localhost]:443 [TCP/IP TLS] -- Connection
refused
---

From the documentation I got the impression that one should enable
verification. And why does this cause a "connection refused"?

Any hints are -as always- greatly appreciated.
