The server is raising here: https://github.com/mwaskom/visigoth/blob/master/visigoth/clientserver.py#L190

The relevant code is

                # Check if we got something surprising
                elif kind != self.SERVER_REQUEST:
                    raise RuntimeError("Unexpected request from the client.")

So we are getting something surprising! But what is it?
