Bug au lancement d’un serveur

Bonjour, récemment j’ai lancé un serveur avec des amis et la première fois que nous nous y somme connecté, tout c’était bien passé mais depuis que nous avons mis des mods, il nous est complètement impossible de se connecter et il y a un message d’erreur disant que le « string » est trop grand (26>20)
Désolé je n’ai pas le message précis mais je peux le trouver si besoin.
Dans les logs, il se passe ça quand on se connecte (je ne sais pas si c’est utile je ne m’y connais pas mais au cas où) :
