I am using a Raspberry pi to host a owncloud server. It uses nginx, and when I configured the pi with this tutorial, the page came up with a 502 Bad Gateway error. I checked the logs and found this:
2015/10/22 05:18:03 [error] 2667#0: *4 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.1.101, server: 192.168.1.102, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "192.168.1.102", referrer: "https://192.168.1.102/"
EDIT: Nevermind this question anymore, I have moved on to using a different platform. However, I am still urious as to what this problem is.
I tried to fix it with several other solutions found in posts on this site like here and here, as well as ensuring that php was installed, but none worked. I am stumped as I am a relative newbie to linux and know nothing about nginx. Any help is appreciated. Thanks in advance.
