Hello,
I've setup a little test environment with varnish5 and hitch as TLS
offloader. HTTP/2 works for me in FF and Chrome (after upgrading to openssl
1.0.2).
I've done the same — Varnish 5 and Hitch — and we're really pleased to
see the initial HTTP/2 support.

So apparently you reached one of the things Varnish doesn't implement
yet, in this case RST frames. Your browser tried to cancel a request
and close the related streams and Varnish doesn't support it.
Spoiler alert, your browser may crash with DATA, PUSH_PROMISE and
CONTINUATION frames.
Part of our motivation for HTTP/2 is to serve map tiles, so we'll have
to wait until RST frames are handled — browsers send these when tiles
are scrolled/zoomed off the map before they've loaded.
I've also hit this error, which may be more interesting as it's a failed
assertion:

But anyway, the server is accessible, should anyone want to fiddle:
- https://api2.gbif-uat.org/v2/map/demo1.html
- http://api2.gbif-uat.org/v2/map/demo1.html
These are both the same instance of Varnish, the first via Hitch, the
second not. The server is in Copenhagen, Denmark, sharing a 1Gbit/s
connection.
I'm following the mailing lists, and will aim to update the server as
more of HTTP/2 is implemented.
Cheers all,
Matt Blissett
