Cancel & Timeout

Abort an in-flight request before its callback fires, or override the default timeout to control how long the client waits for a response.

Cancel

Cancels a pending request. The callback will not be called. Has no effect if the response has already arrived — Cancel is safe to call at any time.

copylocal id = network:Get("slow/resource", nil, function(res)
    print(res.data)
end)

-- Cancel when the player closes the panel
closeButton.Activated:Connect(function()
    network:Cancel(id)
end)

Cancel on player leave

A common pattern: cancel all pending work when the player leaves so cleanup callbacks don't run after the character is gone.

copylocal ids = {}

ids[1] = network:Get("player/data", nil, function(res) UI:Load(res.data) end)
ids[2] = network:Get("shop/catalogue", nil, function(res) Shop:Load(res.data) end)

game.Players.LocalPlayer.AncestryChanged:Connect(function()
    for _, id in ids do
        network:Cancel(id)
    end
end)

SetTimeout

Sets the timeout for all subsequent requests on this network instance. The default is 10 seconds. Call once after getting the network object — it applies globally to this instance, not per-request.

copylocal network = RoExpress.GetNetwork()
network:SetTimeout(5)   -- wait up to 5 seconds before timing out

network:Get("player/data", nil, function(res)
    if res.type == "timeout" then
        UI:ShowError("Server took too long to respond")
    else
        UI:Load(res.data)
    end
end)

What happens on timeout

When a request times out the callback fires with a response where res.type == "timeout". The data and status fields will be nil. Network automatically retries timed-out requests up to the configured maximum — by default 2 retries with exponential backoff — so the callback only fires after all retry attempts are exhausted.

copynetwork:Get("slow/endpoint", nil, function(res)
    if res.type == "timeout" then
        warn("Request timed out after retries")
        return
    end
    -- handle success or error
end)
