我正在使用 AWS ELB 部署 Flask 后端 api。我有一个上传文件的端点和另一个从文件读取数据的端点。

其他每个端点都工作正常，但当我运行读取数据的端点时，上传的文件会运行大约 30 秒，并抛出 502 bad gateway 错误。

ELB错误：2022/03/08 17:30:19 [错误] 25807#25807：*25上游在从上游读取响应标头时过早关闭连接，客户端：172.31.0.71，

.platforms/nginx/conf.d/myconfig。 conf：

keepalive_timeout 3600s;
proxy_connect_timeout 3600s;
proxy_send_timeout 3600s;
proxy_read_timeout 3600s;
fastcgi_send_timeout 3600s;
fastcgi_read_timeout 3600s;
client_header_timeout 3600s;
client_body_timeout 3600s;
send_timeout 3600s;
uwsgi_read_timeout 3600s;
uwsgi_send_timeout 3600s;
uwsgi_socket_keepalive on;

我尝试了很多答案，但没有一个对我有用。请我需要帮助

I'm using AWS ELB to deploy flask backend api. I have an endpoint that uploads a file and another endpoint that reads data from the file.

Every other endpoint works fine but when I run the endpoint that reads data the file that was uploaded it runs for about 30 seconds and it throws the 502 bad gateway error.

ELB error: 2022/03/08 17:30:19 [error] 25807#25807: *25 upstream prematurely closed connection while reading response header from upstream, client: 172.31.0.71,

I have tried a whole lot of answers but none has worked for me. Please I need help
