RPC Eventlogger with HTTPs

Is it possible to configure an RPC event logger to use HTTPS instead of HTTP? The original configuration we used was

{
  type="RPC",
  url="http://localhost:8080/emsNotification",
  serializerType="JSON",
  enabledEvents=
  {
    "outStreamClosed"
  }
}

Now, we configured that the webapp (running on the same host at port 8080) does not allow HTTP anymore and only accepts HTTPS. Therefore, we updated the EMS configuration as follows:

{
  type="RPC",
  url="https://localhost:8443/emsNotification",
  serializerType="JSON",
  enabledEvents=
  {
    "outStreamClosed"
  }
}

However, notifications do not arrive at the webserver anymore. Does EMS support HTTPs notifications? If yes, is there a possibility to accept all certificates in order to also allow self-signed certificates?
