I am running in a similar problem, since updating to Apache 2.4.25.

After a while HTTPS sites stop working, Chrome reports a ERR_SPDY_PROTOCOL_ERROR. Firefox gives a generic SSL error.

I don't quite follow ikkeben's posts, I think they are pointing at an OpenSSL issue.
I don't believe it to be an OpenSSL issue, I have been running 1.0.2e for almost a year with HTTP2 and haven't had any issues until the update to Apache 2.4.25.
I ran through the HTTP/2 commands in this thread to compile everything again is case there was mismatch somewhere.

If I compile Apache without the ""--enable-http2" " bit then it seems to work fine without the SSL sites stopping working.

If anyone has HTTP/2 and Apache 2.4.25 working without issues, I would happy to know how you did it :) In the mean time I think I will look to downgrade Apache to Apache/2.4.23 and see if that resolves the issue.
Sorry thats Dutch-German ;)

I only means i don't know:

So it could be so far i know now somewhere:
OPENSSL
HTTP2 modifications from here.
Custombuild2 / DA
GUI Custombuild2 Martynas.
Apache 2.4.25 Update.
Ofcourse me myself and I ;)

Sure it is a combination of one of more of them. ( Which i don't know)

ONly httpd reload give problem at our VPS, with httpd restart then it seems working correctly, so i made some changes at the directadmin conf saying gracefull-restart=0 then less problems while less httpd reloads. ;).

So i pointed also to this script maybe after the Apache 2.4.25 updates it should with HTTP2 don't httpd reloads sofar this is not solved.
http://files.directadmin.com/services/custombuild/httpd_2

Sorry to have this topic in more threads i realy don't know which one it should be or is responsable for this prob.

this was the update:

I suspect while at our vps the reloads ( gracefull restarts ) are the problem. Not the httpd restarts thes are done correct and give no probs. ( While ALso manual httpd reload is causing problems)

This is in Changelog apache 2.4.25 update > http://www.apache.org/dist/httpd/CHANGES_2.4.25

*) mod_http2: handling graceful shutdown gracefully, e.g. handling existing
streams to the end. [Stefan Eissing]


So maybe.... a kind of BUg / Combo Bug here somewhere
With this one:
So i pointed also to this script maybe after the Apache 2.4.25 updates it should with HTTP2 don't httpd reloads sofar this is not solved.
http://files.directadmin.com/services/custombuild/httpd_2

Update apache 2.4.23 had also some probs before with a older version of this script now maybe...?? > ;)

It's most likely that your OpenSSL does not support ALPN extension, that's why it's difficult to get HTTP/2 running with Apache. Please follow these steps to get HTTP/2 enabled with Apache:
1) Install OpenSSL, with ALPN support:
Code:
wget ftp://ftp.openssl.org/source/openssl-1.0.2j.tar.gz
tar xzf openssl-1.0.2j.tar.gz
cd openssl-1.0.2j
./config --prefix=/usr/local/lib_http2 no-ssl2 no-ssl3 zlib-dynamic -fPIC
make depend
make install

Hi,

I just want to install HTTP/2 on my Apache DA server. But I see that version 1.1.0c is available of OpenSSL.
Is it better to just install version 1.1.0c instead of your mentioned 1.0.2j?

And do I need to use php-FPM to run it correct? This because we use a lot of .htaccess rules.

Thanks!

Someone?

Maybe this is causing it

Hoping this update helps ? no the update to http://forum.directadmin.com/showthread.php?t=54227 doesn't resolved the httpd reload issue with HTTP2 here

Downgrading to 2.4.23 worked for me, been stable for a few days now.

Code:
cd /usr/local/directadmin/custombuild

#create custom_versions.txt
# Add "apache2.4:2.4.23:"
echo "apache2.4:2.4.23:" >> custom_versions.txt


./build apache
You will need to remove it later if you want to upgrade to a newer Apache version.

Thanks Yes but this is not so good while the Apache Update 2.4.25 has also some security fixes! ;)

True, It is more of short term fix and to get the new year out of way.

The mod_http2 bug might be worth a look, I will check my vhosts for "+Indexes" on the sites which I know failed.

results?

See here https://svn.apache.org/repos/asf/httpd/httpd/branches/2.4.x/CHANGES changlog v2..4.26 that is calling i think also this issue.


Changes with Apache 2.4.26

*) mod_http2: fix for possible page fault when stream is resumed during
session shutdown. [sidney-j-r-m (github)]

*) mod_http2: fix for h2 session ignoring new responses while already
open streams continue to have data available. [Stefan Eissing]

*) mod_http2: adding support for MergeTrailers directive. [Stefan Eissing]

*) mod_http2: limiting DATA frame sizes by TLS record sizes in use on the
connection. Flushing outgoing frames earlier. [Stefan Eissing]

*) mod_http2: cleanup beamer registry on server reload, Fixes PR60510.
[Pavel Mateja <pavel@verotel.cz>, Stefan Eissing]

*) mod_ext_filter: Don't interfere with "error buckets" issued by other
modules. PR60375. [Eric Covener, Lubos Uhliarik]

*) mod_http2: fixes https://github.com/icing/mod_h2/issues/126 e.g. beam
bucket lifetime handling when data is sent over temporary pools.

I'm also curious what is causing the problem, and when it will be fixed.
Just rolled apache back to 2.4.23 and everything works again.

Several fixes are made in Apache 2.4.26!

So is this one and a lot more with http2 ..
Changes with Apache 2.4.26

*) mod_http2: regression fix on PR 59348, on graceful restart, ongoing
streams are finished normally before the final GOAWAY is sent.
[Stefan Eissing, <slavko gmail.com>]
Wen fix/update is available i don't know, or DA is providing a FIX in the meantime with the updates/info's out of the svn ??
https://svn.apache.org/repos/asf/httpd/httpd/branches/2.4.x/CHANGES
Why i ask this is while version update 2.4.25 have also some security fixes that the version doesn't 2.4.23 have!?

What is the cleanest way to do this until a structural fix is out? I'm experiencing the same issues since recent upgrades, regrettably I updated nghttp and Apache simultaneously (from 2.4.23) so no further information on which of the 2 is causing it why.

A hard "service httpd restart" seems to fix it properly for now, so simply cronning that after the daily 6:25am sighups could also do the job for now possibly.

[edit] Downgrade procedure documented at https://help.directadmin.com/item.php?id=275 for those Googling it here, just put "apache2.4:2.4.23:" in custom_versions.txt

Without the custom/configure.curl it compiles fine.

I guess you can disregard the above. It seems that my curl has http2 support by default without the mod in this thread:

For Nginx_Apache:
Code:
cd /usr/local/directadmin/custombuild[FONT=Menlo]
[/FONT]mkdir -p custom/nginx_reverse
cp -p configure/nginx_reverse/configure.nginx custom/nginx_reverse/configure.nginx
Build Nginx with statically linked OpenSSL library:
1) Edit configure.nginx which was copied to custom/ folder
2) Add "--with-openssl=/usr/local/src/openssl-1.0.2k" and "--with-http_v2_module" flags
3) Run "./build nginx"
4) Execute:
Code:
cd /usr/local/directadmin/data/templates/
cp -fp nginx_server_secure.conf custom/nginx_server_secure.conf
cp -fp nginx_server_secure_sub.conf custom/nginx_server_secure_sub.conf
perl -pi -e 's#listen \|IP\|:\|PORT_443\| ssl#listen |IP|:|PORT_443| ssl http2#g' custom/nginx_server_secure.conf custom/nginx_server_secure_sub.conf
cd /usr/local/directadmin/custombuild
./build rewrite_confs
My server has LAN_IP and IPv6, but with that config, only the public IP has "http2":

Code:
server
{
	listen 52.15.47.5:443 ssl http2;
	listen 172.31.7.38:443 ssl;
        listen [2600:1f16:5a8:d800:679b:4039:5a5e:98b8]:443 ssl;
        ....
}
how to add http2 to LAN IP and v6 IP
