@ZOS_GinaBruno , @ZOS_KaiSchober , @ZOS_JessicaFolsom , there seems to be a problem with servers... at least 10 more people from my guild got kicked at the same time as the people above too...
The error message seems to have been something like "can't establish connection" too. Login was working sort of.
They could enter the game again after 10-15 minutes.
