The server must be fully started, to be connectable through rcon.

You can modify the Decay-Rate as following:
decay.scale 1.0 is the normal decay rate
decay.scale 0.5 reduces the decay rate by 50%

In example you would like to disable the decay completly, then its required to execute the command
decay.scale 0 press enter after you have entered the command.
You can verify in the console tab now if the command was successfully sent.
To save our changes, its required to send
