Impossibilité pour un joueur de se connecter : Internal Exception: Java.io.IOException: Une connexion existante a dû être fermée par l'hôte distant

Bonjour,

Je possède un serveur Minecraft moddé (114 mods) sur lequel je joue avec des amis. Depuis quelques jours, un d’entre eux a un bug empêchant sa connexion.

Lorsqu’il essaie de se connecter au serveur il apparaît pendant quelques secondes (il voit même les chunks se charger) puis il est automatiquement éjecté du serveur et il voit le message d’erreur :
Internal Exception: Java.io.IOException: Une connexion existante a dû être fermée par l’hôte distant

Cet éjection du serveur arrive uniquement à certaines heures de la journée. Par exemple il ne peut pas se connecter de 21 h à 22h mais il peut à 23h.

J’ai déjà regarder sur internet les causes de ce bug. Cela peut-être la pare-feu, l’anti-virus, la version de Minecraft ou de Java. Il a essayé plusieurs solutions mais aucunes ne marchent. Je le répète, mais ce bug n’arrive qu’à lui. Pour ma part, ce bug ne met jamais arriver et je peut me connecter au serveur pendant toute la journée.

Merci d’avance pour vos réponses

Je vous mets aussi ce que marque la console lorsqu’il n’arrive pas à se connecter :

(On peut voir qu’au bout de 20 secondes, il est déconnecté automatiquement. Ce qui est aussi bizarre
c’est que “Timed out” signifie qu’il est resté AFK trop longtemps, alors que la déconnexion pour AFK est désactivé.)

Essaie de contacter le support via ton panel !
