The provided command line example in example/Example does not work. When running it, none of the logs are processed by the OpenTelemetry Collector and there are no errors within the OpenTelemetry Collector logs.

Additionally, there is a network error when trying to write the logs over gRPC. The port forwarding error is:

When writing only to the HTTP endpoint (4318), there are no errors, but the log is not processed by the Collector.

I think I've figured this one out - I was testing against an HTTPS endpoint and accidentally committed changes to the example with the URL left as https://.... I'll send a fix 😊 sorry!

I verified that the switch from https to http fixes the problem. Will look at PR.
