5.58.146.1 is the precise build.

Hello,

I am not sure what ended up happening with this customer from back in 2018, but it is likely that they stopped responding to me. This may mean that disabling prerequisites boxing worked for them. However, I am having another customer with similar issues.

He has a custom VBA application that uses OPC UA. I believe he is using V2020.2 and the OPC Server is a remote TOP Server.

When he runs his VBA app, he gets the following error:

Run-time error '-2146232832 (80131600)':

OPC-UA service result - Could not create a certificate via a proxy: The
operation complete successfully = Bad.
----SERVICE RESULT ----
Status Code: {Bad} = 0x80000000 (2147483648)

+ The SDK action called was
"ApplicationInstance.CheckApplicationInstanceCertificate"

It would appear that the VBA app cannot generate its certificate and they are not able to try running as admin.

I tried the EasyOpcUADemo and the UAClientCertificateParameters.xls VBA example. Both of these are able to create certificates and place them in C:\ProgramData\OPC Foundation\CertificateStores\UA Applications\certs, but they are also met with errors that read:

Run-time error '-2147024810 (80070056)':

The specified network password is not correct.

+ The SDK action called was
"ApplicationInstance.CheckApplicationInstanceCertificate"

I wanted to recommend disabling prerequisites boxing, but I do not know how to do this for a VBA application. Any thoughts?

I also considered using the Opc.Ua.ConfigurationTool but that looks for an exe extension.

Other thing that we tried was adding this code to his application to set a subject on the client certificate, but no change.

Dim ClientConfiguration As New EasyUAClientConfiguration

ClientConfiguration.SharedParameters.EngineParameters.ApplicationParameters.ApplicationName = "PLACE APPLICATION NAME HERE"

Any ideas or suggestions that you might have would be greatly appreciated.

Regards,
GK

Hello,

I have a user experiencing the same behavior. They are using 5.52.147.1 on two machines and is trying to use the EasyOpcUADemo to connect to their customer's OPC Server. On one machine, they receive the error in the attached screenshot. The other machine makes the connection successfully and can read the nodes. I am told that the only difference is that computer with the error is directly plugged into the customer’s network and that the working machine is connected via their guest WiFi.

This is the full error message:

"The specified network password is not correct.

+ The error occurred while checking the (client) application instance certificate. The certificate generator path was "C:\Program Files (x86)\Software Toolbox OPC Data Client 2018.1\DemoNet\EasyOpcUADemo\Opc.Ua.CertificateGenerator.exe".

+ This is an engine-level error."

The user also showed me a screenshot of the Server Endpoint User Identity and it is set to Anonymous.

Any help would be greatly appreciated.
