WebDriverException while running appium test over HTTPS

[tbalogh]

I encountered the exception below while I was trying to run the example appium test with my app's parameters (testobject_api_key, appium url) over https. I only modified the api key and the server address in the example project. The test works as expected if I change the appium url from https to http.

I created the same project with the java-binding and it works as expected both over http and https.

You can find the repository of the c# and java examples here: https://github.com/tbalogh/testobject-appium-test
