Dedicated Server Failed to start (help me plz)

I'm with the same problem.

 

I was with the same problem, locking for a solve, I found this page from the Kley support: 

https://support.klei.com/hc/en-us/articles/360029882171-Getting-a-Unable-to-write-to-files-in-the-config-directory-Error-Message 
 

The process that worked for me was the 7th. 

 

7) Create a new save directory folder for the game 
If all of the above troubleshooting steps fail, try creating another save directory, separate from your current one (say somewhere else such as c:\DontStarveTogether) and then launch the game with that as the save directory: 
 
- In steam right-click the game in your library 
- Select ‘properties’ 
- Click ‘Set launch options’ 
- Enter ‘-persistent_storage_root c:\DontStarveTogether’ (without the quotes) 
- Close dialog. 
- And the next one 
- Launch the game. 
 

Be afraid if you want to try this process, because I lost all my worlds (I lost a 225+ save), and all my configs became like the first time I opened the game.
