VMM is unable to perform this operation without a connection to a Virtual Machine Manager management server.

Question

Hi,
I'm running SCOM and VMM integration. For the most part everything is working. However I get lots of alerts generated in regards to my scvmm server.
This is a the guide I used:
https://technet.microsoft.com/en-ca/library/hh882396.aspx
SCOM + VMM 2012r2 Ur4
One of the Errors(which appears to be root issue):
The PowerShell script failed with below
exception
System.Management.Automation.CmdletInvocationException: VMM is
unable to perform this operation without a connection to a Virtual Machine
Manager management server. (Error ID: 1615)
Use the Get-VMMServer cmdlet
or the -VMMServer parameter to connect to a Virtual Machine Manager management
server. For more information, type at the command prompt: Get-Help Get-VMMServer
-detailed.At line:109 char:12
+ $vmm = Get-SCVMMServer $VMMServer -Credential
$cred;

Can you connect from powershell? get-vmmserver <VMMServerComputerName>
If this doesn't work it's likely that your VMM server doesn't work. Check Application log to see if there are errors related to VMM service.
You can also collect traces as described
here and attach them to this thread.
Are you using a domain administrator account?  (this is the default allowed after SCVMM is installed - until other users are added).
also try restarting VMM server or VMM services once.
this occur if the SQL database owner is indicated as NULL.  Try adding the SQL SA account as db owner.
refer this once -
