SSIS scheduled job fails

Hi,

I am running an SSIS scheduled job on an SQL Server 2012(SP3 11.0.6260.1) instance. This job is running on-premise and the target is Dynamics 365.  Starting from schedule the job always fail with an "Unexpected empty response". If i start the job manually it runs just fine. I use the same account as the proxy starting the job.

Error message:

"Copy CRM Data:Error: KingswaySoft.IntegrationToolkit.DynamicsCrm.WebAPI.WebApiServiceException: Unexpected empty response received from the resource URL: https://xyz.crm4.dynamics.com/api/data/v8.0/RetrieveVersion ---> System.Exception: Unexpected empty response received from the resource URL: https://xyx.crm4.dynamics.com/api/data/v8.0/RetrieveVersion

Anyone have clue what can be the problem?
