Le nombre de visites sur le site Web est très faible. Il y avait une période pendant laquelle une erreur 504 apparaissait lorsque je revenais après chaque week-end. Plus tard, la fréquence devenait de plus en plus élevée, à partir d'un jour. une semaine à une demi-journée, mais il n'y avait rien dans le code intermédiaire. Gros changement, ça fait bizarre.
Les résultats obtenus en exécutant la commande netstat sur le serveur sont les suivants :
Je ne sais pas comment vous déboguez habituellement ce genre de problème ? Il existe également des sockets de domaine Active UNIX (sans serveurs)
Y a-t-il un problème avec ces deux éléments ci-dessous ?

Si une erreur 504 se produit. Principalement, le temps de demande de service ultérieur de l'entité est estimé comme étant relativement long. En fait, vous pouvez essayer cela en ajoutant quelques paramètres à votre nginx. Utilisez fastcgi ou un proxy inverse pour ajouter un délai d'attente. Il existe également client_header_timeout, client_body_timeout, send_timeout.
