remote event not firing or not being acknowledged?.

Hello, I have made a script which is supposed to be enabling a Screen Gui when conditions are met, i am using a remote event and firing it to the client from my script located in server script service and it is being called on from a local script inside the player Gui. my script works perfectly fine in play mode but when i do test mode the remote event either stops being fired or stops being recieved, please help.

I have tried firing the remote event from the server script outside of any other code blocks and it still doesnt get picked up or / fired.

i have used quite afew print statements to find where the error is located (note i don't recieve any errors in the console).

below is the server script firing the client

for i = 450, 0, -1 do
            wait(1)
            print("bruh")
            roundTimer:FireAllClients(i)
            print(2345677)
            if i == 0 then
                intermissionDebounce = false

            end

here is the local script responsible for detecting the remote event being fired.

roundTimer.OnClientEvent:Connect(function(roundTime)
    print("pie")
    stormGui.Enabled = true
    local timeInSeconds = roundTime
    local minutes = math.floor(timeInSeconds / 60)
    local remainder = timeInSeconds % 60 
    stormTextLabel.Text = minutes .. ":" .. remainder


    if timeInSeconds == 0 then
        stormGui.Enabled = false
        print("bgr")
        menuInitiater:FireServer()
    end
