How to increase nginx request timeout?

Question

My web server processes a huge file and then sends a response. I tried various nginx timeout options with no luck. I tried the parameters recommended in this question , however I still see a timeout page with an error in the nginx error logs.

1 upstream prematurely closed connection while reading response header from upstream,client: 10.0.42.97, server: 

Here is my nginx.conf

 http { include /etc/nginx/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; client_header_timeout 600; client_body_timeout 600; send_timeout 600; proxy_read_timeout 600; fastcgi_buffers 8 16k; fastcgi_buffer_size 32k; fastcgi_read_timeout 600; gzip on; gzip_http_version 1.0; gzip_comp_level 2; gzip_proxied any; gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript application/json; server_names_hash_bucket_size 64; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } 

I still see 502 temporary gateways from time to time, with the indicated error. Any pointers to what might be wrong? My input file is a csv file if that helps. Any pointers or recommendations?

How can i fix this? How to increase the waiting time?

Nginx is not a problem here, it is a script that processes the file you are loading. If you use PHP, you need to change the settings in php.ini in order to provide longer timeout and larger downloads. Possible settings for enlargement can be:

 max_execution_time max_input_time memory_limit post_max_size upload_max_filesize 

If you use a different scripting language, you should look for settings that control maximum load sizes, maximum script runtime, and memory limits. Until Nginx returns errors with errors, as a rule, something is wrong with your processing.
