BadSecureChannelClosed Session.Create

[nimrodch]

Hi,

I want to connect to an OPC IA Server with SignAndEncrypt and RSA128 endpoint.
The Server needs username and password.

Connecting to an unsecure Test-Server (also Auto-accepting its Certificate) works fine and also connecting to the Server with UA Expert works fine.

My Code is based on the .Net SDK by Opc Foundation (Version 1.336). When I try to connect to the Server i get the Exception Result "BadSecureChannelClosed". This happens right after this line:
opc_session = Session.Create(config, endpoint, false,true, "OPC UA Client",10000, uid, prefLoc);







I've tried a lot of settings but i can't find the bug.


I would appreciate any help

Hi,

We are not able to support sample code from the OPC Foundation. The sample code is provided as is and there is no support from the OPC Foundation.

This is one of the reasons why people buy commercial SDKs from Unified Automation. The SDKs are regularly tested at interoperability workshops with hundreds of other implementation and there is a support team that can resolve remaining issues.
