Use -v on the command above to verify that you're checking what you think you're checking. I certain that what is really OK is the default :80 virtual host on that machine. For example, on the machine below, I have nothing listening on port 8080, let alone https --
$ ./check_http -I <redacted> -u https://<redacted>:8080/index.html -v
GET https://<redacted>:8080/index.html HTTP/1.0
User-Agent: check_http/1.89 (nagios-plugins 1.4.3)
http://<redacted>:80https://<redacted>:8080/index.html is 3125 characters
STATUS: HTTP/1.1 200 OK

Makes sense if it's not checking an HTTPS enabled port.

No, I don't expect you need to do that at all.
