The mpm module is not supported by mod_http2

[Konstantinos Adam]

Hello everyone.

I am currently experiencing trouble using http2 protocol.

I already installed mod_http2 via WHM -> EasyApache4 and the apache recompiled successfully.

My hostings using php7.1 and in all of them I have installed AutoSSL.

I see in apache error logs (/usr/local/apache/logs/error_log), the following:

[Sat Jul 29 18:06:16.974193 2017] [http2:info] [pid 899] AH03090: mod_http2 (v1.10.7, feats=CHPRIO+SHA256+INVHD+DWINS, nghttp2 1.20.0), initializing...
[Sat Jul 29 18:06:16.974215 2017] [http2:warn] [pid 899] AH10034: The mpm module (prefork.c) is not supported by mod_http2. The mpm determines how things are processed in your server. HTTP/2 has more demands in this regard and the currently selected mpm will just not do. This is an advisory warning. Your server will continue to work, but the HTTP/2 protocol will be inactive.


Also, in access logs, I see this:

[29/Jul/2017:19:53:50 +0300] "GET / HTTP/1.1" 200 621 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0"

So my requests are using http1.1 protocol instead of http2.

I have disable antivirus and network protection, but with no luck.

I have tried accessing my websites using different computers, different networks (just in case I had a faulty browser or some kind of restriction), but with no luck.

Can anyone please help on this?

Thank you in advance.
