Rcon out of date, how do you update it?

Is there a way to update an outdated Dedicated Server? Because I really don’t want to download the entire thing again. If there is a way to update it, please tell me. Thanks.

…what?

You mean a dedicated server? rcon is just the command use to execute commands on a server. If so, download SteamCMD and update it using these commands: https://developer.valvesoftware.com/wiki/SteamCMD#Downloading_an_app

I’m trying to run my server for Garry’s Mod, but I can’t join (nor’ can anyone else) because it says it’s outdated. Is there a way to update it or not?

Thanks!

You really shouldn’t be hosting a server if you do not know this information.
