standalone OPC-Publisher in Edge Simulator doesn't work

[delema98]

Describe the bug
When starting the opc-publisher in standalone mode in the edge simulator, I get a certificate error (see trace below). The same configuration works on a regular deployed Azure IoT Edge server. Other modules can be simulated.

I tried the latest version as well as the preview 3 version. While the latest version is constantly restarting the opc-publisher module the preview 3 version can connect as a client to an existing opc-server. Outgoing messages (from opc-publisher --> edge runtime) fail.
The following traces are from using the preview version:

Could you post the command line you used to start publisher in the iotedgehubdev context?

I tried it with different command line arguments. The most basic configuration was the following:
"modules": {
"OPCPublisher": {
"env": {},
"restartPolicy": "always",
"settings": {
"image": "mcr.microsoft.com/iotedge/opc-publisher:2.9.0-preview3",
"createOptions": {
"Hostname": "publisher",
"Cmd": [
"--aa",
"--di=60"
]
}
},
"status": "running",
"type": "docker"
}
}

The whole EdgeSolution is based on the default deployment.json and opcpublisher is the only module running

Fixed in preview 4.
