PHP Timeout in nginx

faleddofaleddo Member
in Help

I have troubles configuring website using nginx. Server is randomly timed out even in simple php script. CPU is 95%+ in idle state. Cloudlinux LVE limit also set to unlimited, I maxed the cpu & other LVE limit. Anyone experience this before?
Error log: The timeout specified has expired: AH01075: Error dispatching request to : (polling).

    So? Just configure PHP timeout, either via php.ini or php-fpm pool.d file. Did you asked cgpt?

    put echo on every few lines & inside for / while / other kind of loop

    By any chance, have you checked if there's possibly a script or process running in the background consuming resources? Also, it might be good to look into Nginx configuration for any timeout settings or resource limits that might be causing this.

    Hey, I am no expert, but, I faced a similar issue only a few days ago. This is what got it fixed for me:-

    fastcgi_connect_timeout 120;
fastcgi_read_timeout 120;
fastcgi_send_timeout 120;

    I added this under the location ~ \.php$ block on my nginx configuration file, usually in /etc/nginx/sites-available

    You could also try adding this in your configuration file at the end:-

    proxy_connect_timeout 120;
proxy_send_timeout 120;
proxy_read_timeout 120;
send_timeout 120;

    The value 120 can be changed according to your wish, but, not sure, if higher values are recommended for production.

    Have you tried to check the PHP logs why it timeouts?

    Random guess: this app loads something external and from time to time it fails due to misconfigured IPv6. :cookie:

    CRUD app, database slow? I was having a trouble once with my DB response as the DB server was located on different server and was having some network issues.

    localhost might resolve to ::1 while the database listens to 127.0.0.1. If PHP pursues the database over localhost it won't be happy.

    By the error code, if I am not mistaken, refes to apache error.

    Are you nginx as reverse proxy?

    no heavy background process running. cpu usage is under 10%.> @noob404 said:

    yes, it's nginx as reverse proxy. tried nginx directly as a server too but still not working.

    I'm trying to move to other server that not using cloudlinux now.

    @faleddo If i were you, then I would have started with all the file_get_contents() and start debug from there.

    I hope you are restarting Nginx and PHP after the edits. If you are, pardon me then

    Checkout /var/log/nginx
    It should output some misconfiguration.
