我正在开发一款可供用户上传文件的应用程序。虽然后端调用似乎运行正常,但上传文件时的调用返回 502 Bad Gateway 消息。
文件确实上传了,但出现了错误消息。我认为这与我的 nginx 配置有关,所以我希望你们能指出我哪里出错了。
以下是 nginx 错误日志消息
[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"
这是我的 nginx.conf 文件:

}
我的 conf.d 文件夹是空的,但是我在 sites-enabled 中确实有特定的设置。
这是我的app.com.br.conf:

如果对系统和配置还有其他问题,请告诉我。
提前致谢。
