ConductR sandbox exception

Hi everyone, I have a little problem about conductr usage. When I running my all services on the local environment(via localhost) everything looks fine. When I load my microservices to the conductr sandbox, I sent the same request but I got exception. Any idea ?

{
    "name": "Exception",
    "detail": ""
}

I look it up in the monitoring feature with kibana it gives me:
