I'm using roblox's matchmaking scripts to create my own parties, but when the game starts only the owner is teleported. Then there is an error message saying UserOffline. I don't get why this helps any help?

local arenaPlaceId = game:GetService("AssetService"):CreatePlaceAsync(server.Map.Value..": "..play1, arenaPlaceTemplateId)

	local ownerid = game.Players:FindFirstChild(play1).userId
	if play2 == nil and play3 == nil and play4 == nil then
	else
		local connection = game.Players:FindFirstChild(play1).OnTeleport:connect(function(teleportState, placeId)
			if teleportState == Enum.TeleportState.Started then
				local teleportStarted = os.time()
				for i=1,3 do
					local playz = nil
					if i == 1 then
						playz = play2
					elseif i == 2 then
						playz = play3
					elseif i == 3 then
						playz = play4
					end
					if playz == nil then
						break
					end
					while true do
						local success, error, placeId, arenaInstanceId = teleportService:GetPlayerPlaceInstanceAsync(ownerid)
						if placeId == arenaPlaceId then
							teleportService:TeleportToPlaceInstance(arenaPlaceId, arenaInstanceId, game.Players:FindFirstChild(playz))
							return
						end
						wait()
					end	
				end
			end
		end)
	end
	wait(1)
 	
	teleportService:Teleport(arenaPlaceId, game.Players:FindFirstChild(play1))

Every variable is defined and this is part of a script.
