Inputting RCON Password ingame?

I know what my RCON password is but when I try “rcon_password ****” or even “rcon ****” in my game console, it says Bad RCON password even though its right. Can anyone help?

Make sure the one you’re inputting is the same as the one defined in your servers launch parameters. “-rcon_password asdfghjkl”

Oh and don’t put your room password in your server.cfg
