Forced To Create New Character

[Deluezeonest 0]

Hi Guys, 

So I am having an issue with my dedicated server. After a few days of it running, I will go to log in again and the game will bring up the character creation screen as if I am a new player. I basically lose all of my progress and the game doesn't recognize me as being an existing player. 

Any ideas on how to stop this from happening? 

Thanks
