Failed due to error: Client.IsConnected

Error message

Failed due to error: Client.IsConnected

What it means

Thrown at the start of ArchiHandler.GetMyInventoryAsync (the SteamKit2/GameCoordinator protocol path for fetching the bot's OWN inventory). It asserts the SteamKit2 Client is connected and that Client.SteamID is set before issuing a CEcon inventory request; otherwise it raises a TimeoutException. This is a preflight guard, not a response-handling error.

Solutions

1. Ensure Bot.IsConnectedAndLoggedOn is true before requesting the inventory.
2. Retry the call after the bot re-establishes its session.
3. Check ASF logs for the underlying disconnect reason and resolve it first.
4. Avoid calling inventory methods during startup/shutdown windows.

Example fix

// before
var inv = bot.ArchiHandler.GetMyInventoryAsync();
// after
if (!bot.IsConnectedAndLoggedOn) { /* wait or skip */ return; }
var inv = bot.ArchiHandler.GetMyInventoryAsync();

if (!bot.IsConnectedAndLoggedOn || bot.ArchiHandler.Client?.IsConnected != true)
    throw new InvalidOperationException("Steam client not ready for inventory");

static bool CanFetchOwnInventory(Bot bot) =>
    bot.IsConnectedAndLoggedOn && bot.ArchiHandler.Client.IsConnected
    && bot.ArchiHandler.Client.SteamID != null;

try { await foreach (var a in handler.GetMyInventoryAsync()) { /* ... */ } }
catch (TimeoutException ex) when (ex.Message.Contains("Client.IsConnected")) {
    // session dropped; wait for reconnect before retrying
}

When it happens

Trigger: Calling GetMyInventoryAsync while the SteamClient is disconnected, during reconnect, before logon completes, or right after a dropped connection where SteamID is no longer populated.

Common situations: Code path invoked before OnLoggedOn; calling inventory fetch immediately after Start() without awaiting connection; network blip or Steam restart caused an unexpected disconnect; rate-limit/ban severed the session mid-operation.
