How do we teleport a group of players in a SAME server in a place?

So I have tried with the "reserveServer" function, but it just pops out in the output "HTTP403 "ReserveServer()" Forbidden" or something like that. I've also tried with TeleportPartyAsync() but it doesn't work either. First I thought it could just work in the public game, and not in the studio. I published and tested it on a public server, but it didn't work too. Can you help me, please? Or is there another way to do this? Also, it will be likely to use reserve server, because after teleporting them, nobody else can join them and that's what I want to do.

Make sure the PLACE you are going to teleport into is in the same GAME

If you don't know what that mean A GAME can have multiple PLACES, a starter place where the players spawn and branch places where they can teleport to

if you want to teleport from a GAME to a different GAME, then you need to put id of the STARTER PLACE from the GAME you wan't to teleport to

In order to let a group of players to go to the same place, get the children of Players - GetChildren() or you could make a table with their User ID's , then you can simultaneously teleport them all to the same place in the same game.

function teleport()
 -- teleport players
end

local players = {} -- have their ID's

for i, v in pairs[players] do
       teleport()
wait(1) -- teleport them with 1 second intervals
end

Hope it helps!

OR this might work too!

You can use RemoteEvents to have the client tell the server teleport all the players.

Server

local placeId = 123
local leaderUserId = 1

local partyPlayersList = {
   game:GetService('Players').Player1,
   game:GetService('Players').Player2
}


game:GetService('ReplicatedStorage').TeleportSquad.OnServerEvent:Connect(function(player) -- Connects a function to execute when the "TeleportSquad" event is fired

   if player.UserId == leaderUserId then -- Checks if the player who clicked the start button is equal to the party leader
      game:GetService('TeleportService'):TeleportPartyAsync(placeId, partyPlayersList) -- Teleports all players in "partyPlayersList"
   end

end)

Client

StartButton.MouseButton1Click:Connect(function() -- Connects a function to execute when the client clicks the button
   game:GetService('ReplicatedStorage').TeleportSquad:FireServer() -- Fires the remote event
end)

	for i,v in pairs(game.Players:GetPlayers()) do -- gets every player in the server
	game:GetService("TeleportService"):Teleport(game.PlaceId, player) -- teleports them to the same game
	if player.Character ~= nil then
		player.Character:remove()
	end
end
