I am developing an app where the user can upload files. While the backend call seems to work fine, the call when uploading files returns a 502 Bad Gateway message.
The files actually get uploaded but the error message comes up. I think it has something to do with my nginx config so I am hoping you guys can point out where I am going wrong.
Here is the nginx error log message
[error] 3807#3807: *138 connect() failed (111: Connection refused) while connecting to upstream, client: 189.62.45.133, server: api-dev.app.com.br, request: "GET /users/pics/5218de9eec94a7bb4467c95219b37b41ec1920420c808d9e11244f8d2a234cd6 HTTP/1.1", upstream: "https://161.35.116.108:2000/users/pics/5218de9eec94a7bb4467c95219b37b41ec1920420c808d9e11244f8d2a234cd6", host: "api-dev.app.com.br", referrer: "https://dev.app.com.br/profile"

My conf.d folder is empty however I do have specific setting in sites-enabled.
