Ip: 0.0.0.0

Hi everybody,
i’ve been searching for this error for a long time, and now iam in the dead end.

Somehow my piwik is not showing IP adresses anymore.
Every single record (for every domain) shows:

Fri 14 Dec - 13:16:32
IP: 0.0.0.0
Provider: Unknown

Fri 14 Dec - 13:02:25
IP: 0.0.0.0
Provider: Unknown

Fri 14 Dec - 13:02:06
IP: 0.0.0.0
Provider: Unknown

OS/Browser detection looks correct, but empty IP’s and ofcourse Visitors Location.

Found this thread 301 Moved Permanently , but that’s from version 1.3…
I was so depressed that i already dropped all tables and did clean install of piwik. No change.

Did anyone experience the same problem?
thx

and an Error from Geolocation Settings:

Turned out, problem is caused by hosting provider server architecture, specifically by using nginx.
Thx anyway.

This is a new problem i am hearing now…
