Plutonium doesn't provide game files.

I never said you would get a server key, since that won't be possible.
You don't need a server key to host a server, however all features that depend on it won't work.

I'll give it a try
IW4MAdmin don't seem to work on my end so I'll try with the map vote

VZLAxSmoke knr9

wait so thats all i gotta do

Well, normally that name was from a friend who had a server with me, I am the owner of the vzla server and if I had ddos problems, the only way to solve that is to look for a provider with good ddos protection and I know who the crazy person is who copied your names.

There are a lot of ways to do that depending on the end goal. You can use what was sent above or an IW4MAdmin plugin called DynamicReservoir or use a mapvote like mine

Keep trying until it works or host opens the port on his router to make it work reliably all the time like our doc explains

Reinstall or fix network issue

The feature has since been added to plutonium. You don't need t6-gsc-utils anymore to override the names.
%LOCALAPPDATA%/Plutonium/storage/t6/bots.txt will suffice and can have a name and a clan tag

165.0.0.0/8 isn't a LAN subnet.

you need NAT OPEN , u need to open ports of your wifi router

We don't host servers. Ping is an issue with you and/or the server you're playing on

If you’re hosting the server on the same network you’re playing on, it can be normal for you to not be able to see the server due to your network likely not allowing NAT Loopback. This is explained here: https://plutonium.pw/docs/server/t6/setting-up-a-server/#why-cant-i-find-my-server-hosted-at-home-while-others-can
