Issues with using OPC UA security policy & certificates

[vasudevks]

Hello,

I am experiencing some issues with connecting the Unified Automation OPC UA client to a custom OPC UA server I built. If the security policy is "None", it connects and no error. But if I select encryption or other security type (Basic256 or Basic128RSA125) with the client security certificate, it gives an error: Could not load certificate from file from the path provided. Please find the error log attached for the details. My OPC UA server application creates the server and client certificates.

I would like to know the exact steps to configure the security policy and how to use the certificate files for communicating with the opc ua server. If I can get detailed information on this, that would be a great help.

Thanks,
Vasudev
