[Pecose]

Bonjour tout le monde,

J'ai essayé WaifUPnP mais je rencontre un petit problème.
Voilà l'erreur que je rencontre:

Code :

java.net.SocketTimeoutException: Receive timed out
java.net.SocketTimeoutException: Receive timed out
java.net.SocketTimeoutException: Receive timed out

C'est pas très riche en informations du coup je vous donne le code en entier:

-Déjà, j'ai trouver la source du problème avec un tas de sysout:
