Apache HTTP2 doesn't load page

Hi.
Trying to test HTTP2 on my server v.10.3, but no luck and don't know how to debug and what to do.
Code: 
curl 7.52.1 (amd64-portbld-freebsd10.3) libcurl/7.52.1 OpenSSL/1.0.2k zlib/1.2.8 libidn2/0.16 nghttp2/1.19.0
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smtp smtps telnet tftp
Features: AsynchDNS IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP HTTP2 UnixSockets HTTPS-proxy

HTTP the same

curl -I --http2 https://host.net - no luck. To break I push Ctrl+C

Nothing in access log & error log

What can it be?
 
If there's nothing in the logfiles (are you sure you checked the right ones? On Apache you can have separate logfiles per website) then I think it's safe to conclude that you didn't contact the right machine. Does the DNS record actually resolve to the right IP address?
 
Yes, i have a separate logfile. If I change protocol order configuration in virtual host
from
Code: 
Protocols h2 http/1.1
to
Code: 
Protocols http/1.1 h2
it works well and logging, but over http 1.1 :(
 
Yes, it works over ClearText. So the problem is in TLS.

I use
Code: 
ECDHE-ECDSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH     Au=ECDSA Enc=AESGCM(256) Mac=AEAD
ECDHE-ECDSA-AES128-GCM-SHA256 TLSv1.2 Kx=ECDH     Au=ECDSA Enc=AESGCM(128) Mac=AEAD
ECDHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH     Au=RSA  Enc=AESGCM(256) Mac=AEAD
ECDHE-RSA-AES128-GCM-SHA256 TLSv1.2 Kx=ECDH     Au=RSA  Enc=AESGCM(128) Mac=AEAD
ECDHE-ECDSA-AES256-SHA384 TLSv1.2 Kx=ECDH     Au=ECDSA Enc=AES(256)  Mac=SHA384
ECDHE-ECDSA-AES128-SHA256 TLSv1.2 Kx=ECDH     Au=ECDSA Enc=AES(128)  Mac=SHA256
ECDHE-RSA-AES256-SHA384 TLSv1.2 Kx=ECDH     Au=RSA  Enc=AES(256)  Mac=SHA384
ECDHE-RSA-AES128-SHA256 TLSv1.2 Kx=ECDH     Au=RSA  Enc=AES(128)  Mac=SHA256

and was trying other, all HIGH and MEDIUM, no sense.

aha HowTo said:
Almost all modern browsers support HTTP/2, but only over SSL connections
 
Yes. I wish I paid more attention to your post but your link is correct. While HTTP/2 does not need SSL to work, all browsers that work with HTTP/2 use SSL by default and won't work without it.
