Geolocation Link (under settings) not working

Its very weird what is happening, all installation is working fine, System Check shows all green, but when i click on Geolocation link, i receive a 404 Not Found page, while all other pages are working perfectly.I dont get any other info regarding this error except from my Nginx logs that shows the following :

2013/10/23 09:31:43 [error] 1691#0: *3583 recv() failed (104: Connection reset by peer) while reading response header from upstream, client:, server:, request: "GET /analytics/index.php?module=UserCountry&action=adminIndex&idSite=1&period=day&date=yesterday HTTP/1.1", upstream: "fastcgi://unix:/tmp/php5-fpm.sock:", host: "", referrer: ""

2013/10/23 09:31:43 [error] 1691#0: *3583 open() "/website/html_public/50x.html" failed (2: No such file or directory), client:, server:, request: "GET /analytics/index.php?module=UserCountry&action=adminIndex&idSite=1&period=day&date=yesterday HTTP/1.1", upstream: "fastcgi://unix:/tmp/php5-fpm.sock", host: "", referrer: ""

Also, my real time visitor map is not showing anything, perhaps this is connected with the issue above?
All vistits are tracked though.
Any thoughts what is causing this?
I use Centos.6.4 , PHP 5.5.5 , with Nginx 1.43 , Mysql server 5.5.34-1 , all software is updated to latest version.

Anything in the NGINX error logs?

Matt take a look at my initial post i have nginx logs there

it looked like an access.log not error log… but if there are no more info then we are stuck

No it was the error.log unfortunatelly im having a feeling something has to do with php-fpm but no idea what exactly
