API call is blocked on central server

API call is blocked on central server

Hi,

I want to call getDeviceSuammary and many other device/interface specific endpoints on a Master-slave installation of OPManager. But I get this error mesage in API repsone:

  1. {"error":{"message":"This operation is blocked in Central Server.","code":5004}}
However, The call of  listDevice endpoint returns the correct answer without any error. What's the reason and how could I get details of the devices which are behind probes?

Thanks
