We’re looking at the issue.
Im glad you Devs are looking into the issue. And cutting the character creation due to this issue so no one else has an issue for the time being.
Also, would you be able to submit a game log after seeing this message on screen again? Thanks.
the full log is in your private messages
[ERROR] get new-character failed with status 404
Can you try this again to see if it’s still happening? It should be okay now.
works, both with unpatched and then patched client
