Viewing http://localhost:2899/ shows a confusing 401 error

Because your browser isn't passing anything authentication to it. While technically correct, it's confusing so might as well at least show either a little bit of documentation or an "ok" message.

But what does the error mean? And how can I fix it?

@LudwigHansvon you shouldn't need to fix it and in itself it doesn't indicate anything is wrong with the proxy. It's saying you haven't provided authentication by visiting it directly. When you make requests of it from Observable, we'll include authentication information which shouldn't error.
