Record what each launch actually targets, with active interfaces, source address, selected route and loaded configuration. Confirm the intended endpoint with the network owner. Then compare the same documented read-only request and software version; old success with incomplete notes is not enough to assign the fault.
Check the configuration before anyone disables things at random. Two shortcuts can run the same script name with different targets, and the controller will get blamed for a request that never went to it.
Loaded target matches on both. Network owner confirmed the intended endpoint. Our workshop route selects a different interface from the documented bench connection.
That is a concrete difference to investigate under the approved network arrangement. Does the request trace show it leaving on that selected interface, and what response or timeout follows? Route selection and successful service communication remain separate observations.
