OPC-UA Client: Exception on TCP/IP

Replied by support on topic OPC-UA Client: Exception on TCP/IP
Hello,
Thank you for all the answers. I apologize for not replying earlier. I was trying to come with some cause or a method to diagnose this, but cannot really find anything - short of actually debugging the code on your machine, which I don't think would be possible.
Creating a certificate manually and assigning it to the app is still an option.
I would also suggest upgrading to a newest QuickOPC, although there is no specific fix fot such an issue.
Best regards

I answer to question below(blue):
1. What type of project is your application (e.g. Windows Forms desktop app, Windows service, Web app, Web service etc.)
It's a console application.
2. Does this happen on just one computer, multiple, or all?
it happend only in a windows server
3. Have you installed QuickOPC on the computer using the installation program, or have you just installed the parts of the app yourself?
I install only my application and the license like the other PC where it works fine.
4. What other OPC UA applicatiopns are on the computer?
In this server I install only the Kepware OPC UA server and my application with OPC Labs OPC UA Client to retrieve data from the OPC UA Server.
5. What is the Windows version, and is it 32-bit or 64-bit?
It is a Windows Server 2012 R2 (64 bit)
6. What about the demo application(s) that come with QuickOPC - e.g. the EasyOpcUADemo - do they work, or they show the same problem?
Demo application EasyOpcUADemo work!

Each OPC UA application (client or server) must have an instance certificate, to authenticate itself to other parties. With QuickOPC, you can either provide your own certificate and just let QuickOPC use it, or (by default) QuickOPC attempts to create certificate automatically and then use it. This is the part which fails. Creating and attaching certificate manually is fairly complicated so I would leave it for now unless some other solution is found.
Can you please answer these additional questions:
1. What type of project is your application (e.g. Windows Forms desktop app, Windows service, Web app, Web service etc.)
2. Does this happen on just one computer, multiple, or all?
3. Have you installed QuickOPC on the computer using the installation program, or have you just installed the parts of the app yourself?
4. What other OPC UA applicatiopns are on the computer?
5. What is the Windows version, and is it 32-bit or 64-bit?
6. What about the demo application(s) that come with QuickOPC - e.g. the EasyOpcUADemo - do they work, or they show the same problem?

The OPC QuickOPC-UA version is 5.35.442.1.
I run my application with administrator privileges. What does that mean creating a certificate?

Hello,
which QuickOPC version and build are you using please?
Also, this can be a permissions issue. Creating a certificate or placing it into a store usually requires administrative privileges. Try to run the client with elevated privileges, or use an alternative method to create and place the certificate.
Regards
