Hello, I am using opc ua client node in node red. I have kepwareX as opc server and I have set basic256sha256 to my opc server endpoint. Now I want to use certificate in the opc ua client, but problem is I am running node red on ubuntu virtual machine and my opc server is in windows. And opc ua client is demanding certificate path what should be solution for this?
