SSL alert number 40 is normally because you're supposed to provide a 
valid client certificate, which you didn't give. So it can check the 
server certificate, but the server complains it cannot check yours.

Unfortunately, I don't think you can pass a client certificate to 
check_http, so I guess you'll need to reconfigure your server so it 
doesn't require a client certificate for this check (some mix of Satisfy 
Any, Require valid-user and Allow from nagios-host might do the trick 
for Apache).
