NGINX + HTTP/2 working partially - nginx

I just compiled a custom version of nginx for our new project.
NGINX -V:
nginx version: nginx/1.9.15

On the browsers from my work office http2 works fine. When I go home and test on my pc, http2 does not work in any browser. I cannot understand where the problem is.
I have the same windows 7, same browsers, everything the same.
Can somebody point me out the problem I am facing ?
Many Thanks.

Can think of two reasons why this might happen:
You are using anti virus software at home which performs MITM interception to enable it to scan traffic. See here: https://serverfault.com/questions/752767/trying-to-setup-http2-on-apache.
You are using a LoadBalancer or other such infrastructure that sits in front of your nginx server, when accessed externally.

nginx: [emerg] unknown "bytes_received" variable

I try to log the amount of bytes received from a client in Nginx like so:
log_format postdata '$remote_addr sent $bytes_received bytes';
However, I get the following error when attempting to start the service:
nginx: [emerg] unknown "bytes_received" variable
As far as I can see this variable should be present from Nginx 1.11.4. I run 1.13.9:
#:/usr/local/nginx/sbin/nginx -v
nginx version: nginx/1.13.9
Output of nginx -V:

Is there something I am missing here?
Thanks for any help!
PS: Using answers as comments as I need to post large text
Seems like you have it compiled from source and a required module is missing. I have below output on the same
configure arguments: --with-cc-opt='-g -O2 -fPIE -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2' --with-ld-opt='-Wl,-Bsymbolic-functions -fPIE -pie -Wl,-z,relro -Wl,-z,now' --prefix=/usr/share/nginx --conf-path=/etc/nginx/nginx.conf --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --lock-path=/var/lock/nginx.lock --pid-path=/run/nginx.pid --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --with-debug --with-pcre-jit --with-ipv6 --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_auth_request_module --with-http_addition_module --with-http_dav_module --with-http_geoip_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_image_filter_module --with-http_v2_module --with-http_sub_module --with-http_xslt_module --with-stream --with-stream_ssl_module --with-mail --with-mail_ssl_module --with-threads
So make sure you have all the stream modules at least and may be some other module is a pre-requisite for this to work
$request_length may be what you want:
request length (including request line, header, and request body)
This logs the size of the request received from the client without hitting the unknown variable issue, if you're using a build of Nginx which doesn't have ngx_stream_core_module built in.
In other words $request_length (rather than $bytes_received) seems to be the counterpart to $bytes_sent, somewhat confusingly.

How can I prevent nginx from serving http/2?

I am working on implementing http/2 for an ecommerce website my company made. I'm hosting it on debian jessie and found that it's now pretty easy to get nginx from the backports repo which was built against openssl 1.0.2 to support ALPN (which is necessary these days to work with chrome).
So I upgraded my libssl and then my nginx. To my great surprise, nginx now seems to be serving my content through http2 even though I didn't add that keyword to the config. Chrome's dev tools show h2 in the protocol column of the network tab.
Normally I would be happy about that, but I'd like to make some comparison measurements between http1.1 and http2. How can I force it to serve http1.1 again (temporarily) to make my measurements?
Edit: adding output of nginx -V to be specific about my version

According to the documentation:
The http2 parameter (1.9.5) configures the port to accept HTTP/2 connections.
Thus any virtual server configured on this port will accept HTTP/2 connections. If you want to configure some hosts with HTTP/2 but other without, then you have to use different IP or ports.

Install push stream module for nginx

I need to install push stream module for nignx.
cd /
wget http://nginx.org/download/nginx-1.7.12.tar.gz
tar -xvf nginx-1.7.12.tar.gz
cd nginx-1.7.12
git clone http://github.com/wandenberg/nginx-push-stream-module.git
next...

Check you nginx install:
nginx -V
This command view all compile options etc.
You will can check nginx-push-stream-module module
Your build looks good so I'd be checking that you don't have multiple nginx binaries in your $PATH that your service could be executing instead of your new build.
whereis nginx
You've installed your new binary into /usr/local/sbin, so check you haven't forgotten to remove older nginx distributed packages that could interfere.
rpm -qa | grep ^nginx
If all else fails, move the git repo out of your nginx source and try again:
git clone https://github.com/wandenberg/nginx-push-stream-module.git
wget http://nginx.org/download/nginx-1.7.12.tar.gz
tar -xvf nginx-1.7.12.tar.gz
cd nginx-1.7.12

make && make install
Even better, if you want to automate builds this is what I use on my servers:

Hope it helps!

why does spdy not function here with nginx 1.5.10?

i have compiled nginx 1.5.10 with the spdy module on centos 6.5 and it is operating without a problem, as far as i know except, that spdy is apparently not being used.
i have added the 'spdy' option to the listen directive in nginx.conf and restarted the server, yet the various spdy checking methods, such as the firefox plugin that is available and also the website: https://spdycheck.org/
both show that spdy is not being used on my site.
the line in nginx.conf is:
listen 443 ssl spdy default_server;
i saw this thread: How to set up SPDY Protocol over Nginx?
and looked to see if i needed to change the DAEMON or PATH lines in /etc/init.d/nginx - yet in my versions those lines are not present at all.
the output of nginx -V is:

any tips welcomed!
SPDY/3.1 isn't supported by Firefox 26. The support was added to Firefox in version 27, see release notes.

minimal nginx installation from source?

I am using drupal 7, nginx with SSL, php-fpm to serve static pages. I would like to get the maximum security & speed from my nginx installation. Thats why I have decided to install it from source and leave unnecessary modules. can someone help me to select the modules please? here is what i am choosing...
./configure --user=nginx --group=nginx --prefix=/etc/nginx
--sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_geoip_module --with-http_ssl_module --with-http_gzip_static_module --with-http_secure_link_module --with-pcre --without-http_uwsgi_module --without-http_scgi_module --without-http_autoindex_module --without-http_ssi_module --add-module=pagespeed
