None of my scripts are showing for others?

None of my scripts are showing for other players inside the server, even though they are fired of :FireAllClients, via the server script.

Local Script:

local RS = game:WaitForChild("ReplicatedStorage")
local plr = game.Players.LocalPlayer
local player = game:GetService("Players")

local canbeused = true


local streamaraiangrande = {"Looks like the host / co-host forgot to put a message here, haha! Lucky for you already ahead of you.","It appears that the host / co-host forgot a message here, woopsies!","It appears that the host / co-host forgot a message here, woopsies!"}

-- buttons function of UI lol xd xd xdr wararwarrar

if plr:HasAppearanceLoaded() then
	script.Parent.LeftTopPanel.username.Text = plr.Name
	script.Parent.LeftTopPanel.rank.Text = plr:GetRoleInGroup(8176838)
else
	script.Parent.LeftTopPanel.username.Text = "Loading!"
	script.Parent.LeftTopPanel.rank.Text = "It appears that we havent loaded yet!"
end

-- security + opening of the UI

if plr:GetRankInGroup(8176838) >= 50 then

		script.Parent.LeftTopPanel.Close_B.Visible = false
	end)



else
	script.Parent.PanelMain.Visible = false
end

Server Script:

local ReplicatedStorage = game:GetService("ReplicatedStorage")

game.ReplicatedStorage.T_Remotes.Session_Remotes.Send.OnServerEvent:Connect(function(player)
	game.ReplicatedStorage.T_Remotes.Session_Remotes.Receive:FireAllClients("Session Host: " .. player.Name)
end)

game.ReplicatedStorage.T_Remotes.Session_Remotes.Send.Send2.OnServerEvent:Connect(function(player)
	game.ReplicatedStorage.T_Remotes.Session_Remotes.Receive.Receive2:FireAllClients("Session Co-Host: " .. player.Name)
end)

game.ReplicatedStorage.T_Remotes.Session_Remotes.AnnouncementSend.OnServerEvent:Connect(function(player)
	game.ReplicatedStorage.T_Remotes.Session_Remotes.AnnouncementReceive:FireAllClients("text")
end)

game.ReplicatedStorage.T_Remotes.Session_Remotes.AnnouncementReceive.OnServerEvent:Connect(function(plr,text)
	local FilteredMessage = game:GetService("Chat"):FilterStringForBroadcast(text,plr)
	if plr:GetRankInGroup(8176838) >= 210 then
		game.ReplicatedStorage.T_Remotes.Session_Remotes.AnnouncementReceive.ATransfer:FireAllClients(plr,FilteredMessage)
	else
		warn("This does not work with your rank." .. plr.Name)
	end
end)

game.ReplicatedStorage.T_Remotes.Session_Remotes.GetPlayer.OnServerEvent:Connect(function(moderator,plr)
	if plr:GetRankInGroup(8176838) >= 210 then
		game.ReplicatedStorage.T_Remotes.Session_Remotes.GetPlayer.GP2:FireAllClients(plr)
	else
		warn("Your not high enough rank wise." .. plr.Name)
	end
end)

All suggestions would be appreciated. B)

Still having same issues, tried a few different methods and still appear to have the same issue.

Nope. image

Still experiencing issues with this. [Bump]
