Re: [milo-dev] Milo Client Bad_ServiceUnsupported
Cool, thanks for the hint. This is what I was looking for.

You are of course free to call it on your own as well.

Hi Kevin - Thanks for your fast response. This is really appreciated.

You are right, when I use the complete URI (opc.tcp://<IP>:<PORT>/<SERVER_NAME>) it works. Before I just used opc.tcp://<IP>:<PORT>.

When I use opc.tcp://<IP>:<PORT> in the Prosys Client it show a “Select Server” dialog. Is there also a way to discover the server names with Milo?

This is indicating the server is returning Bad_ServiceUnsupported in response to a CreateSessionRequest, which doesn't really make much sense.

Are you using the same endpoint URL as when the Prosys client connects?

Can you get a Wireshark capture of both Milo connecting and the Prosys client connecting?

Hi All,

I have some problem connecting to a Siemens OPC UA server (Milo version 0.3.7). It is failing in the connection stage (client.connect) with “UaServiceFaultException: status=Bad_ServiceUnsupported, message=The server does not support the requested service.”.

Prosys OPC UA client can connect without problems. Anybody has a clue what the issue could be?

Thanks a lot.
