Support of the server is not your responsability but in that case there is absolutely no error just empty window after connecting. Is there a way to debug this?
Version 2 of your client worked, version 3 does not (but works agains your demo server). Tge clienbt is in fact connected to the server and wireshark shows that they exchanging info all the time without error. It is only the display which is broken.
1* is there a way to make your client log more info about what is happening?
2* What can it be?

I just ran python server-example-py from the python-opcua project so it is easy for anybody to test

btw isnt’t there a possibility attach a screenshot to the forum? I cannot find it…

Hi,

There’s indeed no functionality to attach screenshots here to the forum.

The screenshot would probably be informative so please send a screenshot to us by email to uajava-support prosysopc.com

you should have recevived a screenshot showing the issue. The client is connectetd (With encryption NoneNone) and is asking all the time for server status. (The answer packet is vidsible in wireshark)

Hi,

Seems this is a bug in the client application, or more techincally in the SDK in situations where the server does not send certificate (which is ok for None security mode connections). In practice it craches with a NPE in such way that the UI does not work. Will be fixed for next version (for the SDK and client application). Beta versions can be asked by mail if needed.
