[Ayushi-shah1]

I am using the latest OPC twin module of image URI as mcr.microsoft.com/iotedge/opc-twin:latest in IoT edge which running in Windows VM. But the OPCTwin is unable to detect OPC UA server. I am getting repeatedly same logs. Below is the log of OPC Twin.

Try setting the "User": "ContainerAdministrator", in the twin module's container create options. E.g.

{
    "Hostname": "twin",
    "User": "ContainerAdministrator",
    "Cmd": [
        "PkiRootPath=/mount/pki"
    ],
    "HostConfig": {
        "Mounts": [
            {
                "Type": "bind",
                "Source": "C:\\mount",
                "Target": "C:\\mount"
            }
        ]
    }
}
