Cloudfront

Hm. Upload a file with <?php var_dump($_SERVER); ?> to check if the header is set.

If it is set, but empty, then it simply couldn’t determine your country (can happen in rare cases).

If it is not set, maybe this helps:

Can’t tell you more details as I didn’t use AWS yet …

The server header that needs to be in there is called CloudFront-Viewer-Country (as in your first screenshot). It isn’t, so there is something that needs to be fixed in your AWS config.

Unfortunately I never used AWS yet, and the documentation doesn’t tell quite, so your best bet is to contact their tech support about it. Alternatively, you can choose a different source.
