I have installed Nginx and php7.1-fpm on Ubuntu 16.04. It was working perfectly fine. I am started getting 504 Gateway Time-out
error.
When I checked the Nginx log, I got this errors:
*1 upstream timed out (110: Connection timed out) while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: server.name,, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.1-fpm.sock", host: "example.com", referrer: "http://example.com/"
Here is my virtual host file
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name example.com;
root /var/www/example/public;
index index.html index.htm index.nginx-debian.html index.php;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
try_files $uri /index.php =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}
Please guide why I am getting this error. How can I resolve it.
