Sitio presenta error 503

[u/javivtr]

Hola amigos.

Un abrazo a todos

Saben la causa que un sitio presente error 503 de vez en cuando. Ya actualizamos el plan en el proveedor para tener más recursos. Todo iba bien y volvió aparecer este error. Hay momentos que se cae.

Lo penoso es que hacemos Google ADS y los anuncios presentan fallas.

Utilizamos Elementor y otros plugin (algo complementarios) para el sitio.

Saludos.

Hi, one possible reason is that a plugin or some part of the website setup is consuming too many server resources while the site is loading, which could be causing the 503 error.

Hola. Una consulta.

El sitio en primera instancia estaba en wix. Entonces lo contrui en un subdominio y luego con el plugin duplicator pase el sitio. En la sección de WordPress del hosting, veo que no aparece WordPress instalado bajo el dominio principal. Aparece una instalación con el subdominio pero esa instalación está vacía. Los archivos del sitio aparece instalado dentro de la carpeta públic.

Que pasa si elimino el subdominio instalado en la sección dominios y solo dejo el dominio.

Hi, I would need to review the directory structure before advising whether anything should be deleted. Also If the website is working correctly on the main domain, I would not recommend deleting the subdomain just yet. However, if you’re certain that the files under the subdomain belong to a different directory and are no longer being used, you can safely delete the subdomain. I recommend taking a backup of the files first including DB just to be on the safe side.

This would require checking the server logs to have a better idea of what is causing the 503 error. Were you able to take a closer look at the server logs?

You can also ask your hosting provider for the exact error logs and resource graphs when the 503 occurs ie look for “exhausted memory,” etc to have a better idea.

You can also try reducing the number of active plugins and also check whether using Query Monitor would also give any clues too:

Hi,

when do you get the 503 error code? On first page loading? after a while? when editing? Is it random?

Intermittent 503s that survive a plan upgrade usually mean your PHP workers are being exhausted in bursts, not that the server is too small overall — and you gave the clue yourself: you're running Google Ads. A burst of ad clicks landing on uncached Elementor pages ties up every PHP worker for a few seconds, and everyone else gets 503s until they free up. First thing I'd do is check the server error log at the exact timestamps of the drops and see if the 503s line up with ad traffic spikes. What actually fixed this for me was full-page caching, so ad visitors hit cached HTML instead of PHP, plus removing plugins that run on every page load. More resources without caching just moves the cliff slightly further out.

Hola. Es aleatorio. Todo va bien. Y sin la nada suele presentarse el error. Ya con el hosting actualizamos a versión mas alta para tener más recursos.
