websocket problem with ssl(h2)

i have a running actix server based on the websocket-chat example. everything works fine. but when i add ssl support, i can't connect with a client based on examples/websocket/src/client.rs. i get an error "Error: Tunnels are not supported for http2 connection". the browsers still work fine with h2. without ssl chrome is using http 1.1, with it h2. i now there was some problem with the websocket/h2 story in the past...

is there a way around this, or a way to force HttpServer or Client to use http 1.1 ?
