The forums here are for the QuickOPC product of OPC Labs. It looks like that you are using a product from Unified Automation, therefore I suggest that you contact their technical support.

Best regards

Exception thrown "certificate is not trusted" was created by Savage
Using the UA sample "Client Full", I am getting an exception (UnifiedAutomation.UaBase.StatusException) saying "Certificate is not trusted".
The exception is thrown and caught in the program's MainForm, and I do not see the TrustCertificateDialog as expected.
I have exported the certificate and added it to the Trusted Root Certification Authorities store.
The exception message includes the thumbprint, which I used to check that the certificate is in the store.
(By the way, the program I'm connecting to, and from which the certificate was exported, happens to be Industrial Gateway OPC Server)
