Well, once again HedgeDoc does offer demo server/free web version and have a list of intended for public use servers (although they are not so easy to properly register on). But I agree that the service is young and not quite as reliable as HackMD. Infact, they cannot guarantee that the notes won't be deleted. In any case, gotcha!
Here's their support forum where you can describe the problem in detail and have someone guide you through the process.
There's also a matrix chat for quick questions
In fact there's an ongoing tread about the docker image at the moment
