[Chocorean]

Can you join your config file authmod-server.toml, if there is one?
Do you have write access to the folder you're running the server in?

[BlackcatCXII]

authmod-server.toml

yes i have access

[Chocorean]

Did you manage to find anything?
Did you try deleting world/serverconfig/authmod-server.toml and rerunning the server?
