[HELP] LEMP Server Timeout Error.

Question

Hi,

I have a 4GB Raspberry Pi 4 and I have mounted a LEMP server, with a domain in Namecheap, following this guide: https://www.techcoil.com/blog/how-to-host-a-wordpress-website-on-a-raspberry-pi-with-raspbian-buster-lite-and-nginx/

Right now, we have a clean WordPress installation without installing additional plugins or themes.

The error we are having is that when trying to access the web, sometimes it gives a Timeout error, and at other times it works fine. It usually happens on the first connection, and once the main page loads, you can move through the menus and load quickly.

For testing, one way to check is with PageSpeed Insights, and it usually gives “FAILED_DOCUMENT_REQUEST” error or takes a long time to load “Speed Index”.

The website is https://dualbix.com

Any ideas?

Thank you.

Hi there @dualbix , There are a few things which could be causing the problem: The DNS change was made recently and you still need to wait for the DNS cache to clear over the Globe There are some issues with Nginx and it is not running, in this case, I could suggest following the steps from this answer here on how to troubleshoot common Nginx problems: https://www.digitalocean.com/community/questions/how-to-troubleshoot-common-nginx-issues-on-linux-server Your firewall is blocking the traffic on port 80 and/or 443 - in this case, you need to make sure that the 2 ports are open I can see that your WordPress installation is now up and running. Would you mind sharing here with the community how did you get this to work? Regards,Bobby

The intermittent timeout and slow-loading issues you’re experiencing with your WordPress site on a Raspberry Pi 4 LEMP server could stem from various factors, particularly performance limitations and configuration. Here’s a comprehensive approach to troubleshoot and resolve these issues: 1. Check Server Resource Usage Raspberry Pi 4 has limited resources (4GB RAM, ARM processor), and WordPress can be resource-intensive. Monitor CPU and RAM: Use htop or top to check server load: htop Monitor Disk I/O: Use iotop to check if disk operations are causing delays: sudo apt install iotop sudo iotop 2. Optimize Nginx Configuration Ensure your Nginx is optimized for low-resource environments: Open your Nginx configuration file (/etc/nginx/nginx.conf) and set reasonable limits: worker_processes auto; worker_connections 1024; keepalive_timeout 10; client_max_body_size 64M; server_tokens off; gzip on; gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript; gzip_min_length 256; Restart Nginx. 3. Tweak PHP-FPM Settings WordPress heavily relies on PHP, and poorly configured PHP-FPM can cause timeouts. Open /etc/php/7.x/fpm/pool.d/www.conf (adjust 7.x to match your PHP version): sudo nano /etc/php/7.x/fpm/pool.d/www.conf Update the following: pm = dynamic pm.max_children = 10 pm.start_servers = 3 pm.min_spare_servers = 2 pm.max_spare_servers = 4 These values are optimized for low-resource systems like Raspberry Pi. Restart PHP-FPM: sudo systemctl restart php7.x-fpm 4. Database Optimization Enable Query Cache in MySQL/MariaDB: Edit /etc/mysql/mariadb.conf.d/50-server.cnf and add: query_cache_size = 16M query_cache_limit = 1M query_cache_type = 1 Check for Slow Queries: Enable the slow query log and investigate: SET GLOBAL slow_query_log = 'ON'; Optimize Tables: Run: sudo mysqlcheck -o --all-databases 5. Enable Caching in WordPress Caching can drastically reduce server load and improve response times. Install a Caching Plugin: Consider lightweight caching plugins such as: WP Super Cache W3 Total Cache Static File Cache: Configure Nginx to serve cached pages: location / { try_files $uri $uri/ /index.php$is_args$args; } Check Logs for Clues Review server logs for timeout errors or warnings: Nginx Logs: sudo tail -f /var/log/nginx/error.log PHP-FPM Logs: sudo tail -f /var/log/php7.x-fpm.log
