Marco ... is there a need to use TLS ? TLS make it much harder because you have to make sure that the certificates being used on the endpoints are accepted on all places whcih can call that endpoint. So to make things easier and at least to show everything is working you could better disable TLS and use TCP (or maybe UDP depends on you needs and how the netwokr people think about UDP. Lots of company network rules have some kind of restrictions on UDP traffic so to be on head of that netter use TCP even when it is more overhead and slower).
