Reserve server players ending up in the same server?

So I am trying to make a lobby which teleports the players who are in a tube into the same server using reserve server. The way I'm trying to do it, and correct me if this is horrid, but I have a remotevent which fires to the client, back to the server, creates a table of all the players and teleports them. This does work but then a new player teleports, he gets put in the same game as the previous players. I do not receive error codes, or any sort of warning.

This is the teleporting script:

local teleportService = game:GetService("TeleportService")
local code = teleportService:ReserveServer(6879552528)
local teleportPlace = 6879552528


script.Parent.TeleportingEvent.OnServerEvent:Connect(function(player)
    local Playerr = {}
    table.insert(Playerr, player)
    teleportService:TeleportToPrivateServer(teleportPlace,code,Playerr)
end)
