Server timing out while trying to upload and process XLS file
I'm running a Laravel small app which processes a uploaded XLS. Out of a sudden it started giving a 502 error. My Nginx log only says
2017/09/14 17:45:54 [error] 1896#1896: *1 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 22.214.171.124, server: 126.96.36.199, request: "POST /admin/importar HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.0-fpm.sock:", host: "188.8.131.52", referrer: "http://184.108.40.206/admin/importar"
I tried many things, including increasing timeout time and buffer size in PHP.ini or in nginx config file
Any idea on how I could solve this?
The xls file is about 1 MB and the app runs smoothly locally
