Here's the log for running about a minute. I've noticed in the file system that my application is creating a cert if that was what you were wondering, it's simply the server not creating them.
Thank you,
Connor Frayne

Hello,
regarding the certificate creation issue:

I do not think it is your code causing this - but I do think it is the System Restore that is at fault.

It would be useful to know what is the error that prevents QuickOPC from generating the certificate (the error you provided is from the OPC AU configuration utility, which can be the same thing, but we cannot be sure). Does your program report any error? If not, can you please hook to the static EasyUAClient.LogEntry event, and collect the event entries generated when the certificate should be create (and is not)?

Also, although the error message is different, I think it would be worth checking the permissions on the C:\ProgramData\Microsoft\Crypto\RSA folder - as it was with the issue described here: kb.opclabs.com/Error_%22The_specified_network_password_is_no...ey_container_was_not_found.%22 . And try the Resolution steps, if the permissions are not as they should be.

And I also recommend to check the permissions on the certificate store folders.

Best regards

Yes,
in this case I think there is little that can be done/has to do with the client side of things.

The status code (BadWaitingForInitialData) is not something that the client has made up. It is what the client has received from the server. So if the server is sending the client this status code, and you think it is not appropriate, the investigation should start at the server side.

I will reply to the certificate-related issue separately later.

Best regards

Hello,
By looking through connectivity explorer I found that all my tags were "BadWaintingForInitialData", to me this seems like a separate issue but it could help you in knowing the issue so I'm posting it here.

This seems to be an issue with our OPC server provider so I'll go through them with this.
Thank you,
Connor Frayne

Certs malfunctioning after system image restore was created by CFrayneIonic
Hello,
After doing a system image recovery on a faulty machine, I tried reinstalling my application on the device and I'm having some strange Cert issues, the application doesn't seem to correctly generate its certs. This specific issue hasn't happened before on other devices none of which have been image restored, which leads me to believe it was the image restore causing this; However, it is possible that my code is the source as I do do AES crypto in my code.

Im on QuickOPC 2024.1
Here are the only application parameters I set:
EasyUAApplication.Instance.ApplicationParameters.ApplicationManifest.ApplicationName = "SafeBox"
 EasyUAApplication.Instance.ApplicationParameters.ApplicationManifest.InstanceIssuerStorePath = "C:\\Program Files (x86)\\SafeBox\\OPC Foundation\\CertificateStores\\UA Certificate Authorities"
 EasyUAApplication.Instance.ApplicationParameters.ApplicationManifest.InstanceOwnStorePath = "C:\\Program Files (x86)\\SafeBox\\OPC Foundation\\CertificateStores\\Machine Default"
 EasyUAApplication.Instance.ApplicationParameters.ApplicationManifest.InstanceTrustedStorePath = "C:\\Program Files (x86)\\SafeBox\\OPC Foundation\\CertificateStores\\UA Applications"
 EasyUAApplication.Instance.ApplicationParameters.ApplicationManifest.RejectedStorePath = "C:\\Program Files (x86)\\SafeBox\\OPC Foundation\\CertificateStores\\RejectedCertificates"
Thank you,
Connor Frayne
