How can I use curl with a SSL URL to get a 200 OK?

I'm trying to use curl to get the HTTP status of a GET request:

curl --insecure --silent --show-error --connect-timeout 1 -I https://host:8443/health

Note: I'm using the --insecure flag in this command.

I get the following output:

HTTP/1.1 403 Forbidden
Server: Apache-Coyote/1.1
Pragma: No-cache
Cache-Control: no-cache
Accept-Ranges: bytes
Last-Modified: Wed, 16 May 2012 03:05:24 GMT
Content-Type: text/html
Content-Length: 1234
Date: Wed, 16 May 2012 08:57:30 GMT

When I navigate to this URL in a browser, it works fine and I get a 200 OK.

How can get a 200 OK from the curl command? Can I export the PEM cert from the browser and use it some way?
