When monitoring the SSL service on a host that runs HTTPS but not HTTP, Icinga warns about a 403 Forbidden return code. But that warning is for HTTP, not HTTPS.
Manually running the check_http command with either -S or --ssl returns a 200 OK code (and a 403 Forbidden response when run just against HTTP).
But the automated service check returns a 403 error with either switch -- check_http!-S or check_http!--ssl.
Icinga does not complain about other SSL hosts monitored using this service check, perhaps because they all run HTTP also.
Icinga uses the Nagios plugins, so I think this is either a Nagios or (more likely) a configuration issue.
How to fix this erroneous report? The SSL service is working on the host.
This is for Icinga 1.7.1-7 running on Debian wheezy. Thanks!
