NGINX *7060 upstream timed out (110: Connection timed out)

I had this error today with my NGINX on Vutr, with php7:

2017/08/22 07:46:09 [error] 19191#19191: *7060 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 111.11.11.111, server: somedomain.com, request: "GET /com$

I did a hard reset of the server and now everything is working fine. But what was it, why it happened and will it happen again?

This is my nginx.conf:

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

        #custom added 22.08.2017
        proxy_read_timeout 300;
        #end custom
        client_max_body_size 800m;

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        # server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        ##
        # SSL Settings
        ##

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;

        ##
        # Logging Settings
        ##

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        include /etc/nginx/sites-enabled/*;
}

Finally, i found the issue!

I had too many processes at the same time.

the problem was in php-fpm settings.

so this error I had in php logs: (so if u have same problem check php logs) enter image description here

On the web I found this article.

After I add change my www.conf file:

pm.max_children = 40

Then I restart the php-fpm:

systemctl restart php7.0-fpm.service
