To get access to the remote admin panel of your server, you will need to become admin, so follow these steps :
- Get your SteamID
 - Activate your SCP server
 - Go to the "files" page
 - Navigate in these folders :
".config/SCP Secret Laboratory/config/12345/"
(12345 should be your server port number) - Click the "config_remoteadmin.txt" file
 - Then add yourself as admin by replacing "SomeSteamId64" by your SteamID, so you become the server owner.
 - Save the file and restart your server
