Please support monitoring when using https

Is your feature request related to a problem? Please describe. Only becomes a problem if you enable SSL, and at that point it is a blocker

Describe the solution you'd like When starting with https, fix the web monitoring healthcheck script to use the correct curl invocation

Describe alternatives you've considered Works ok without https/SSL

Here's a hacked version of the healthcheck script suitable as fuel for a legitimate PR:

Note it's a complete HACK, because I didn't retain compatibility with the old plain-text http monitoring method.
