dell - Cannot connect to OMSA on ESXi server

I have vSphere ESXi installed on a Dell R710 and am trying to setup and connect to dell OpenManage Server Administrator. I have successfully installed the Dell OpenManager 8.5.0 for esxi650 package, it shows up in the package list, but trying to connect to the server ip at port 1311 (using http or https) is just ending up with a refused connection.

Things I've already tried:

• Starting the CIM Server service, my understanding is that this is
  service that actually handles the web server.


• Connection to the CLI via SSH and manually modifying the firewall
  
  rules to open port 1311.


• Installing OpenManager Server Administrator onto an Ubuntu VM and using that VM to access OMSA.

I'm still not 100% sure I understand OpenManage and how it's supposed to work, but I'm fairly certain that after it's installed on a machine you can access that OMSA on it by opening up a browser and going to "https://[machineaddress]:1311". This worked perfectly fine when I installed OMSA on the Ubuntu VM, but since the Ubuntu VM doesn't actually have any dell hardware it didn't do any good.

I've seen a number of screenshots of people connecting to OpenManage and it giving them the option to specify what server they want to connect to such as this one, but I've never been able to get such a screen. I was hoping to get such a screen when I created the Ubuntu VM and installed OMSA there.

• Is this what I'm missing?
  
  
  
  
  
  • If so, is there a way to get to that screen from an Ubuntu OMSA install or does it require a windows server install?
  
  


• Alternatively, did I have it correctly to start and I should be able to connect to the ESXi host at port 1311 with a browser to access OMSA?


• Is this possibly an incompatibility between ESXi 6.5 and Dell R710s? ESXi 6.5 apparently isn't supported on R710s. It's gonna suck to have to re-install the VM host, but I'll do what I need to in order to get full functionality.

Of course, any other feedback is also welcome and appreciated. I've spent most of 2 days trying to troubleshoot this and have come up empty.
