WinRM connection errors

So I have two physical client access servers and one of them has lost connection to the EMC and has intermitten connection using the EMS. When I run a command using the EMS for example 'get-clientaccessarray' it will return the results . If I try to run the same command again straight away I get the following error message:

Starting a command on remote server failed with the following error message : The WinRM client cannot process the reque
st. It cannot determine the content type of the HTTP response from the destination computer. The content type is absent
 or invalid. For more information, see the about_Remote_Troubleshooting Help topic.
    + CategoryInfo          : OperationStopped: (System.Manageme...pressionSyncJob:PSInvokeExpressionSyncJob) [], PSRe
   motingTransportException
    + FullyQualifiedErrorId : JobFailure

I then cannot run any other powershell commands on the EMS for a few minutes and then I can run a command once again and then get the above error message again. How can I get access back using the EMC and resolve this intermittent WinRM error?

I am getting the following system error in event viewer, not sure if its related:
