Hi @BiggoB

you have two ip-addresses - ipv6 and ipv4.

But they send different content.

A non-existent file: ipv4 sends a 404, ipv6 sends a 200 - http status.

[Address Type=IPv4,Server=nginx,HTTP Status=404] vs [Address Type=IPv6,Server=nginx/1.4.6 (Ubuntu),HTTP Status=200]

So remove your ipv6 address in your dns settings or configure your nginx, that ipv6 is used.
