Abstract: A method, apparatus, and computer program product provide for network communication error originator identification with a header, such as an HTTP header. In the context of a method, the method causes a service request from a NF client to be transmitted to a NF server via one or more intermediary network proxy functions. The method receives a service response with error information identifying the type or identity of the originator of the error response or identifying the type or identity of network proxy function having relayed the error response. The method may also be enabled to redirect a service request to a different NF server or a different network proxy function, and to enable the NF client to determine whether to redirect the request to a different NF server or a different network proxy function.
