I've done almost everything on the internet to gzip my content. It does not seem to work. I've done so much that I can't possibly put everything I've tried here, so here's some of the things I've tried:
I've tried adding this into my .htaccess and I also tried adding it into my apache2.conf and restarting apache.
<IfModule mod_deflate.c>
# Compress HTML, CSS, JavaScript, Text, XML and fonts
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
AddOutputFilterByType DEFLATE application/x-font
AddOutputFilterByType DEFLATE application/x-font-opentype
AddOutputFilterByType DEFLATE application/x-font-otf
AddOutputFilterByType DEFLATE application/x-font-truetype
AddOutputFilterByType DEFLATE application/x-font-ttf
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE font/opentype
AddOutputFilterByType DEFLATE font/otf
AddOutputFilterByType DEFLATE font/ttf
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE image/x-icon
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/xml
# Remove browser bugs (only needed for really old browsers)
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
Header append Vary User-Agent
</IfModule>
They both don't work. I'm on an AWS EC2 Ubuntu server with Apache.

I found the answer... finally!
It was in this code that was something like this:
SetEnvIfExpr no-gzip
It was in my apache2.conf file. Once I removed that code, it worked!
Apache2 say:
One further directive AddOutputFilterByType is still supported, but deprecated. Use dynamic configuration instead.
First I thought that better to use AddOutputFilter directive.
However solution found at How to enable gzip compression on Apache show enough anew way to configure mod_deflate.
Lookalike:
<IfModule mod_mime.c>
AddType application/x-javascript .js
AddType text/css .css
</IfModule>
<IfModule mod_deflate.c>
SetOutputFilter DEFLATE
<IfModule mod_setenvif.c>
SetEnvIfNoCase Request_URI \.(?:rar|zip)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.(?:gif|jpg|png)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.(?:avi|mov|mp4)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.mp3$ no-gzip dont-vary
</IfModule>
<IfModule mod_headers.c>
Header append Vary User-Agent env=!dont-vary
</IfModule>
</IfModule>
Read subj for a varies.
Example of Apache 1.3 mod_gzip module mean just:
<ifModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>
And my humble opinion that the part about really old browsers is not very reliable part of your .htaccess …
