Connection between the container modules fails due to a certificate error #27

- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

Cloned the sample, updated env, built and pushed the deployment.template.json, created the deployment for my edge device. Modules are being deployed to the device but it seems like the Camera Capture Module can't establish a connection to the Image Classifier Service.

Any log messages given by the failure

Expected/desired behavior

Running custom vision service.

OS and Version?

Raspbian stretch 9.6

Mention any other details that might be useful

It seems like the SenseHatDisplay module is not pushed to the Azure Container Registry and therefore can't be found by the Edge Device. However, I don't have such a display on my pi anyway so I don't really care about that module.

In the meantime I set up another Pi with a clean installation of the newest Raspbian and Edge-Runtime and got it running on this device. So the error above might be related to incompatabilites with previous versions of the IotEdge-Runtime. Therefore I'm closing the issue now but suggest to add some hints regarding the necessary version of the edge runtime to the documentation.

@MaWa19 got it, thanks for the follow up!
