Hi, which version of the UA-SDK is it, please?

[prrw]

Hello, it is UA .NET SDK version 3.0.0. Please see the link below. It already has some examples which i listed in the previous message. I compiled it with Visual Studio 2015 just for information. https://www.unified-automation.com/products/server-sdk/net-ua-server-sdk.html

working well ... maybe you did not trust the certs with moving the cert file on UA server side
