I set up the server a few minuts ago and everything worked and i could also connect to it. After adding EasyAdmin (wich i could load via putty) i wanted to add it to server.cfg. I restarted the server to load new config and i got this errors.
Path: /home/FiveM/Server & /home/FiveM/Server-Data
The server.cfg is located in Server-Data.
Edit: The problem was, i wasnt in folder Server-Data with putty
