When using the ProxyHandler and LoadBalancingProxyClient to send a request to a backend HTTP server that supports HTTP/2 the server responds with a 503 instead of routing the request.
I've written an SSCCE here: https://github.com/codemonstur/loadbalancer-bug
When line 38 is commented out (i.e. HTTP/2 is not enabled on the backend) the request succeeds normally and I get the "Hello, world!" message. When the line is left in I see this error:
