How do I turn off KeepInventory?

[Twikai]

I'm playing on a server with friends and when anyone dies they keep their inventory, and i want to turn it off. I've tried using /gamerule keepinventory false multiple times and restarting the server but it's still on. Any idea how to fix this?

Maybe type that command into the console

you need to do /gamerule keepInventory false

because the capitalized I matters, anyways you don't need to restart the server after updating gamerules

I've tried doing it in the console and with the capitalized I but it still doesnt actually work

You must be in the world you want it in, when you execute the command.
