Why do you need it? The public part of the certificate gets transferred to the server during the communication setup. So according to what you wrote, you already have it in the Kepware server.

But, if you really want to get to your certificates, consult the documentation:

- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...html#Certificate%20Stores.html

Unless you have special needs, all QuickOPC-based applications generate client certificates for themselves automatically and you do not have to do anything.

If you do not not know to operate the OPC server side, you need to consult the documentation to the server, or contact their support.

AFAIK, the Kepware server will put the client's certificate to its Rejected certificates list, and there is a command in its user interface to move a rejected certificate into Trusted certificates.

Best regards

Thanks for your reply.

The screenshot I shared with you for the information to show which application I am using.

I am using kepware server in a remote machine. I created an inbound rule and an outbound rule for the 49320 port.

The firewall is running.

In the kepware server, It was requesting a client certificate to trust the client.

Please guide me further on how to proceed to establish a connection between the easy OPC UA Client to connect with the kepware OPC UA Server at the remote machine.

Right now, I am using easyUAOPCDemo ( C# examples Visual studio) for the OPC UA Client from the OPC Labs

with regards,

Hello.

I do not understand this part of your report: "The actual reason I was not able to generate Certification for my client.".
There is nothing in the error messages that would indicate a relation to a certificate problem.

The error message means that failure happens when a TCP connection is being established to the target server. And there is no response. Usually this means a mistaken address, or that the server is not running, or is not configured to listen on the specified port, or there is a firewall in between that blocks the connection.

Best regards
