[Problème] authentification très lente sur mon serveur minecraft (VPS)

Bonjour,
J'ai un soucis depuis quelques temps, j'ai loué un hébergement vps chez OMGserv.



J'ai donc installé un serveur minecraft sous debian 7 minimal suivant la vidéo
Le tutoriel a bien fonctionné, mais au moment de me connecter à mon serveur minecraft, le serveur met une 15 aine de secondes à apparaitre comme en ligne (dans le menu des serveurs sur minecraft)

J'ai évidement contacté le support mais ils n'ont rien pu faire.
En pensant que le problème venait de OMGserv, je suis allé chez VPSZ

A ma grande déception, c'était le même problème...
J'ai essayé plusieurs versions de spigot (1.8.8,1.8,1.7.10)
J'ai également essayé plusieurs façons d'installer un serveur sous debian 7 minimal.
Ensuite, j'ai pensé que ça pouvait être un problème de port, j'ai donc essayé plusieurs ports.
Encore une fois le support n'a rien pu faire.

je me tourne alors vers vous pour savoir si quelqu'un pourrait m'aider.

Sur ceux, je vous souhaite une excellente journée.
Iban

 

Les moments où l'attente est longue:

 

Oui j'arrive à me connecter au serveurs environ 15 secondes d'attente.
