I’d probably just use messaging service.
You can send pretty much any data to a server using it, in this case player id’s / names depending on how you want to go about it.

I havent actually tried this so the following code might error, also it won’t work if multiple servers are trying to get players. You could probably fix that with a unique MessageID and be fine but yeah.

local MessagingService = game:GetService("MessagingService")
local Players = game:GetService("Players")
local ServerID = game.JobId

function GetAllPlayersFromRunningServers()

	local AllPlayers = {}
	local MessagingConnection
	local LastMessageRecievedTime = 0
	local StartTick = tick()
	
	MessagingConnection = MessagingService:SubscribeAsync("GetAllPlayers", function (PlayerData)
		table.insert(AllPlayers, PlayerData)
		LastMessageRecievedTime = 0
		StartTick = tick()
	end)

	MessagingService:PublishAsync("SendAllPlayers", {JobID = ServerID})
	
	while task.wait() do
		LastMessageRecievedTime += tick() - StartTick
		
		if LastMessageRecievedTime > 3 then
			MessagingConnection:Disconnect()
			break
		end
	end
	
	return AllPlayers
end

MessagingService:SubscribeAsync("SendAllPlayers", function(Message) --got message from a server to send all your players over
	if Message.JobID == ServerID then -- make sure we dont send our own players (unless you want to)
		return
	end

	local PlayerData = {}

	for _, Player: Player in Players:GetPlayers() do
		table.insert(PlayerData, {Name = Player.Name; UserID = Player.UserId}) --packing these both into a table just in case you want either or
	end

	MessagingService:PublishAsync("GetAllPlayers", {PlayerData = PlayerData; ServerID = ServerID}) --
end)

print(GetAllPlayersFromRunningServers())

Why not to use for i loop?
it’s so much easier and less complicated than this
