Gzip not working - NO_MATCHING_SCHEME - iis

Question

Problems with activating Gzip on IIS 8 on a windows server 2012 (standard)
So i activated the compressions in the windows features
I checked both checkboxes in IIS - compression (dynamic and static)
But still no Gzip available. However, on my localhost machine (just a windows 10) this works.
What i do see, is that the gzip temp directory (C:\inetpub\temp\IIS Temporary Compressed Files) is getting filled up when i browse my site via the server localhost. BUT strangely enough i'm not seeing anything Gzip-ped in chrome.
The only headers (in chrome) are: HTTP/1.1 304 Not Modified Accept-Ranges: bytes ETag: "0a354779de8d11:0" Server: Microsoft-IIS/8.0 X-Powered-By: ASP.NET Date: Thu, 28 Jul 2016 13:41:04 GMT
(Even yslow is saying no gzip is activated)
When i remove the gzip temp folder, and browse to the site trough the 'official' website url, then nothing is even generated.
Does anyone has any idea what is going on here?
I added this in my web.config
<httpCompression>
<staticTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="image/jpeg" enabled="true" />
<add mimeType="*/*" enabled="false" />
</staticTypes>
<dynamicTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="image/jpeg" enabled="true" />
<add mimeType="*/*" enabled="false" />
</dynamicTypes>
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" dynamicCompressionLevel="4" />
</httpCompression>
See this other topic, where i activated more log information, Gzip not working, server 2012, IIS 8
All i get is:
<RenderingInfo Culture="nl-BE">
<Opcode>STATIC_COMPRESSION_NOT_SUCCESS</Opcode>
<Keywords>
<Keyword>Compression</Keyword>
</Keywords>
<freb:Description Data="Reason">NO_MATCHING_SCHEME</freb:Description>
</RenderingInfo>

Can you try adding this to your web.config file ?? I suggest so because it worked for me on IIS windows shared hosting. Its similar to your code with a few changes...
<system.webServer>
<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
<dynamicTypes>
<add mimeType="text/*" enabled="true"/>
<add mimeType="message/*" enabled="true"/>
<add mimeType="application/javascript" enabled="true"/>
<add mimeType="application/javascript; charset=utf-8" enabled="true"/>
<add mimeType="application/x-javascript" enabled="true"/>
<add mimeType="*/*" enabled="false"/>
</dynamicTypes>
<staticTypes>
<add mimeType="text/*" enabled="true"/>
<add mimeType="message/*" enabled="true"/>
<add mimeType="application/javascript" enabled="true"/>
<add mimeType="application/javascript; charset=utf-8" enabled="true"/>
<add mimeType="application/x-javascript" enabled="true"/>
<add mimeType="*/*" enabled="false"/>
</staticTypes>
</httpCompression>
<urlCompression doStaticCompression="true" doDynamicCompression="true"/>
</system.webServer>
I'm not sure if you need to add
<add mimeType="image/jpeg" enabled="true" />
Isn't jpeg a compressed format ? You could add it none the less if you wish to.
[OPTIONAL]: I read this at MaxCdn.
Origin servers should include Vary: Accept-Encoding, and here’s how:
<system.webServer>
<httpProtocol>
<customHeaders>
<remove name="Vary"></remove>
<add name="Vary" value="Accept-Encoding"></add>
</customHeaders>
</httpProtocol>
</system.webServer>
You can add this bit to your web.config file as well, deploy and check it in the request headers through your browser's developer tools itself.
