Why isn't messaging service sending the information to other servers?

I am making something that requires cross server communication, and I found messaging service to be what I was looking for. So I tried it on my phone and on my computer, but it only worked on the device that I pressed the button on. Anybody know why?

remote.OnServerEvent:Connect(function(player, Testmessage)
	local success, errormes = pcall(function()
		return messagingService:SubscribeAsync("TestMessage", function(message)
			print(message.Data)
		end)
	end)
	
	if success then
		errormes:Disconnect()
	end
	
	local Publishsuccess, Publisherrormes = pcall(function()
		local function message()
			Testmessage.Visible = true
		end
		messagingService:PublishAsync("TestMessage", message())
	end)
end)

You should put this outside the remote connection.

Like this

repeat
local success, errormes = pcall(function()
	return messagingService:SubscribeAsync("TestMessage", function(message)
		print(message.Data)
	end)
end)
wait(5)
until success

remote.OnServerEvent:Connect(function(player, Testmessage)
	local Publishsuccess, Publisherrormes = pcall(function()
		local function message()
			Testmessage.Visible = true
		end
		messagingService:PublishAsync("TestMessage", message())
	end)
end)

.

And also, what is this?

#3

The function or the publishAsync()?
because the function is to make the message visible, and the publishasync i got off the api

#4

Put the SubscribeAsync outside the OnServerEvent

Anyways, I gave you the code already.

Okay thanks I’ll try it out right now

edit: it did the same thing as before

#6

The code I sent you is the proper way to do it. The reason it only works for the player that did the function, is because of this

Anyways, talking about MessagingService. MessagingService:PublishAsync only takes a string as the parameter. The message() function returns nothing, and since you called it, it returns nil. Even if you accidentally put a (), you can’t pass a function.

A solution is to make action-value string or just string value itself.

messagingService:PublishAsync("TestMessage", message()) -- You are calling the function, which returns nothing

messagingService:PublishAsync("TestMessage", "Message blah #123") -- You should pass a string, or call a function that returns a string.

Then in the SubscribeAsync, you recieve that passed data and get it using message.Data.

local success, errormes = pcall(function()
	return messagingService:SubscribeAsync("TestMessage", function(message)
		print(message.Data)
	end)
end)

Using that data you got, you can create cross-server events or actions. In your case, you want Testmessage to be visible, then you can do this

local success, errormes = pcall(function()
	return messagingService:SubscribeAsync("TestMessage", function(message)
		print(message.Data)
		if message.Data == "Message blah #123" then
			Testmessage.Visible = true
		end
	end)
end)

Sorry for the late response, but that does make a lot more sense. thanks
