Enabling Service Bus and SAP built-in connectors for stateful Logic Apps in Standard

Hi edwardyhe , 

i am having some issue with above setup, i currently have a logic app standard which uses service bus built-in connector, it i set the property WEBSITE_PRIVATE_PORTS = 2 on my logic app instance, i see one of my workflows which uses a blob trigger do not move ahead after the trigger stage and shows up as running and i need to cancel the run.  in other workflow where i have service bus peek lock trigger, the trigger gets fired but there is no new instances on the run history. 

if i remove this setting, then my logic app starts working only issue that i face is the workflow cannot complete/ dead letter the message. 

any suggestion how this can be fixed?

the error i see on app-insight is : The listener for function 'Functions.WorkflowDispatcher' was unable to start. An attempt was made to access a socket in a way forbidden by its access permissions.
