-------------------------------------

Hi Torsten,

Well I thought I knew what the problem was but now I'm not too sure. I have 
tested running Milo with both dev/0.6 and release/0.6.0 branches but both seem 
to be able to connect.

When you start the Milo server does it list the endpoints such as this:-
{code:java}
20:02:20.244 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://localhost:12686/milo to 0.0.0.0:12686 [None/None]
20:02:20.245 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://localhost:12686/milo to 0.0.0.0:12686 [Basic256Sha256/SignAndEncrypt]
20:02:20.245 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://localhost:12686/milo/discovery to 0.0.0.0:12686 [None/None]
20:02:20.245 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://172.20.10.3:12686/milo to 0.0.0.0:12686 [None/None]
20:02:20.246 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://172.20.10.3:12686/milo to 0.0.0.0:12686 
[Basic256Sha256/SignAndEncrypt]
20:02:20.246 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://172.20.10.3:12686/milo/discovery to 0.0.0.0:12686 [None/None]
20:02:20.246 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://127.0.0.1:12686/milo to 0.0.0.0:12686 [None/None]
20:02:20.246 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://127.0.0.1:12686/milo to 0.0.0.0:12686 [Basic256Sha256/SignAndEncrypt]
20:02:20.246 [main] INFO  o.e.m.o.stack.server.UaStackServer - Binding endpoint 
opc.tcp://127.0.0.1:12686/milo/discovery to 0.0.0.0:12686 [None/None]

{code}
Is the localhost address in there? Can you try connecting with 127.0.0.1 or the 
machines host name? Although when you mentioned that it returns nothing for the 
getEndpoints call, it may be a permissions issue?

What OS are you using?
