Console Client Sending Empty Endpoint URL

When I connect the console client to a specific endpoint URL it connects but in the TCP Hello message it sends an empty endpointUrl parameter, causing the connection to be rejected by the server.

Why isn’t the endpoint URL being included?

Am I not contacting support here? Laugh

This is a 3rd party server and the Prosys sample console client. It’s pretty cut and dry: the sample console client isn’t sending an endpoint url in the Hello message.

Yes, sorry, I was a bit unclear. I mean that it would be easier to handle this via email. We will contact you.

How was this exception solved? I encountered the exactly same error when I used prosys opcua client library to connect to a third party server. I tried to set the endpoint url by setting the EndpointDescription. It did not help.
EndpointDescription endpointDesc = new EndpointDescription();
endpointDesc.setEndpointUrl(getServerUri());
this.opcUaClient.setEndpoint(endpointDesc);

BTW, I used “Prosys OPC UA Client” program to connect to the server, I got error “Cannot discover applications from opc.tcp://…”.

This was an interoperability problem with the server. If the client cannot connect then the server is not available in the defined connection address (or is not working properly).
