Hace unos minutos en el foro de diablo :

We're aware of issues affecting our authentication servers which may cause players to experience failed or slowed logins (e.g. getting stuck at "Retrieving Character List"). We're currently investigating the cause of these issues and have brought all Diablo III game servers offline for maintenance. We will provide updates as they become available.

Thank you so much for your reports!


A esperar a que arreglen el problema >.<
