In addition, there appears to be some problem with the certificate that has already been generated - I suggest you clear all certificates related to your app from the stores.

Hello.

The relevant message in the log is:
Exception: {System.UnauthorizedAccessException} Access to the path 'C:\ProgramData\OPC Foundation\CertificateStores\RejectedCertificates\private\OPC2SQL [FC6D42C5C14333F373945E42AD47014723164AEB].pfx' is denied.
So, you need to make sure that permissions exist (for the user that is running the app) to access the listed path.

Best regards

Hello,

unfortunately, since you are using version 5.54, and there were changes in newer versions in this area, plus an improved diagnostics, I cannot help you further.

Recommended action is to rebuild and test with current version, and if that works, version upgrade. If it does not work, it should at least give better diagnostics.

Best regards

Hi,
I tryed with and without admin privilege, but the error is the same. I tryed also to move the folder with exe file and dlls from C:\... to Desktop, but doesn't communicate.
The log is the same with and without admin privilege.

I tryed also with EasyOpcUADemo of OPC Labs and this program on this VM working fine.

Hello,
thank you.

Have you tried the first suggestion (running with elevated privileges), and what were the results. Or, is the log file actually from that run?

Best regards

Hello,
thank you, this is very good, that's what I needed - at least for start.

The error tells us that there is some problem creating (auto-generating) the OPC UA application instance certificate for the client (your application). This happens before an OPC UA connection is even established.

1) Try to run the application with elevated privileges ("Run as Administrator") once.
2) if that does not help: Please add an event handler to the static EasyUAClient.LogEntry event, and capture all log messages generated during the (failed) start of your application.

Best regards
