Hello,

nginx is the HTTP server that is provided with my home automation software, jeedom. It is installed on my Raspberry Pi2.
Everyting is working fine, I can connect from my internal network and from outside.

But, when connecting from work, I get an error (navigator displays and certificate issue ...).

I had a lool to the logs and here is the corresponding entry in /usr/share/nginx/www/jeedom/log/nginx.error:
2015/04/16 18:38:27 [error] 2151#0: *38577 upstream timed out (110: Connection timed out) while reading upstream, client: 109.99.99.99, server: , request: "GET /socket.io/?EIO=3&transport=websocket&sid=qY83EqT2TTpBpiTzAAIn HTTP/1.1", upstream: "http://127.0.0.1:8070/socket.io/?EIO=3&transport=websocket&sid=qY83EqT2TTpBpiTzAAIn", host: "truc:4321"
2015/04/16 18:42:05 [error] 2150#0: *39108 upstream prematurely closed connection while reading response header from upstream, client: 109.99.99.99, server: , request: "GET /socket.io/?EIO=3&transport=polling&t=1429202405657-73&sid=lxHkscjGEw5l1p2YAAI8 HTTP/1.1", upstream: "http://127.0.0.1:8070/socket.io/?EIO=3&transport=polling&t=1429202405657-73&sid=lxHkscjGEw5l1p2YAAI8", host: "truc:4321", referrer: "https://truc:4321/jeedom/index.php?v=d&p=history"

Of course 109.99.99.99 is my remote IP and "truc:4321" my domain name / port !

I am not sure this only log may help, but many thanks if you were kind enough to provide me some help to understand and fix my issue. I can do some more tests and provide other logs, just let me know what I should do.

Thanks !
