Neuron 3.6 local address could not be found

I've been doing some testing with Neuron 3.6.0.920.

I have a solution running on my local machine that I have upgraded from 3.5. I tested and invoked the services using my machine name (localhost is blocked by the firewall) but I get the following error on runtime 3.6

<Fault xmlns="http://schemas.microsoft.com/ws/2005/05/envelope/none"><Fault xmlns="http://schemas.microsoft.com/ws/2005/05/envelope/none"> <Code> <Value>Receiver</Value> <Subcode> <Value xmlns:a="http://schemas.microsoft.com/net/2005/12/windowscommunicationfoundation/dispatcher">a:InternalServiceFault</Value> </Subcode> </Code> <Reason> <Text xml:lang="da-DK">The current service instance for the 'https://dk-udlan3-hp840.kamstrup.dk/api/v1/customers/0451770I?domain=D045' url could not be found </Text> </Reason> <Detail> <ExceptionDetail xmlns="http://schemas.datacontract.org/2004/07/System.ServiceModel" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <HelpLink i:nil="true"/> <InnerException i:nil="true"/> <Message>The current service instance for the 'https://dk-udlan3-hp840.kamstrup.dk/api/v1/customers/0451770I?domain=D045' url could not be found </Message> <StackTrace>at NeuronEsb.Server.Runner.ESBClientConnector.SetClientConnectorState(Message p1) at NeuronEsb.Server.Runner.ESBClientConnector.ProcessMessage2(Message p1) at SyncInvokeProcessMessage2(Object , Object[] , Object[] ) at System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs) at System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage11(MessageRpc& rpc) at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet) </StackTrace> <Type>System.Exception</Type> </ExceptionDetail> </Detail></Fault>

Any suggestion? Should I change anything in the Endpoint hosts configuration or somewhere else?

Thanks
