Error message

Failed!

What it means

In ArchiWebHandler.GetInventoryAsync (the HTTP inventory path, used for foreign inventories or as a fallback), when the requested steamID is 0 (meaning 'use the bot's own ID'), ASF waits up to ConnectionTimeout seconds for the web session to Initialize. If it never initializes, an HttpRequestException(Strings.WarningFailed) ('Failed!') is thrown. This is a session-readiness timeout, not an HTTP call failure.

Solutions

1. Wait until Bot's web session is initialized before requesting inventory.
2. Increase ASF's ConnectionTimeout.
3. Ensure the bot is logged on (check IsConnectedAndLoggedOn) before the call.
4. Retry after the session refreshes; resolve any underlying login/access-token errors first.

Example fix

// before
var inv = bot.ArchiWebHandler.GetInventoryAsync();
// after
if (!bot.ArchiWebHandler.Initialized) { /* wait for session init */ return; }
var inv = bot.ArchiWebHandler.GetInventoryAsync();

if (steamID == 0 && !bot.ArchiWebHandler.Initialized)
    throw new InvalidOperationException("Web session not initialized; cannot fetch inventory");

static bool CanFetchWebInventory(Bot bot, ulong steamID) =>
    steamID != 0 || bot.ArchiWebHandler.Initialized;

try { await foreach (var a in webHandler.GetInventoryAsync()) { /* ... */ } }
catch (HttpRequestException ex) when (ex.Message == Strings.WarningFailed) {
    // session init timeout; wait and retry
}

When it happens

Trigger: Calling GetInventoryAsync(steamID: 0) while the bot's web access token/session is not yet initialized, and it fails to initialize within ConnectionTimeout seconds, or the bot is no longer connected/logged on during the wait (the loop also stops if Bot.IsConnectedAndLoggedOn becomes false).

Common situations: Calling inventory fetch during startup before web session refresh completes; access token expired and refresh keeps failing; login disconnected mid-wait; ConnectionTimeout too short under slow networks.
