So what _do_ you see? I tried again just now and it works fine for me. Add "--trace-ascii dump2" and attached that dump2 file for us to take a look!

Can you really negotiate ALPN with that OpenSSL version?

My test version reports this:

$ ./src/curl --version

** [bugs:#1429] http/2 headers/body printing**
**Status:** pending-needsinfo
**Labels:** http2

It seems in some scenarios curl is not printing out request/response headers and body content.  For example the following request is invalid and correctly prints out the response headers:
>$ curl --http2 -k 'https://10.0.2.2:13443/proxy/address' -d 'INVALID CONTENT' -i
HTTP/2.0 400
server:http2query2
However the following 2 requests are valid but does not print out any response headers:
>$ curl --http2 -k 'https://10.0.2.2:13443/proxy/address' -d 'VALID CONTENT' -i
$
$ curl --http2 -k 'https://10.0.2.2:13443/proxy/address' -d 'VALID CONTENT' -s -D -
$
Also the body is not printed in the second case.
