From my OME server I tried using my IP addresses and this: https://myipaddress:1311
Could not get to any of my servers, just timed out.
Just to give more information - when I run OMSA on that web server it gives me the all the usual stuff. That server is running Windows Server 2008 R2
I have another server (not running IIS) that is running Windows Server 2008 that OMSA works fine and OME discovers and inventories correctly (it told me i needed a firmware update on my PERC card!)
