Binance Futures account state request failed

Error message

Binance Futures account state request failed: {e}

What it means

refresh_account_state calls the Binance Futures HTTP query_account endpoint; any transport/API error is logged and re-raised as 'Binance Futures account state request failed'. It is invoked during connect, so a failure here aborts client startup.

Solutions

Inspect the inner error (logged via log::error!) to identify the Binance error code and fix the root cause.
Verify API key/secret and that the key has Futures trading permissions enabled.
Check network connectivity/proxy and that your IP is on the key's whitelist.
Sync system clock (NTP) if the error indicates timestamp out of recvWindow.

Defensive patterns

Strategy: retry

Validate before calling

if api_key.is_empty() || api_secret.is_empty() {
    return Err(anyhow::anyhow!("missing Binance API credentials"));
}

Try / catch

match client.refresh_account_state().await {
    Ok(state) => state,
    Err(e) if is_retryable(&e) => {
        tokio::time::sleep(Duration::from_secs(2)).await;
        client.refresh_account_state().await?
    }
    Err(e) => return Err(e),
}

Prevention

Enable Futures permission on the API key before deploying.
Sync server clock with NTP to avoid recvWindow errors.
Whitelist the host IP on the API key.
Log the inner error code for diagnosability.

When it happens

Trigger: query_account() returns an error: network failure, invalid/expired API keys, missing futures permissions, IP whitelist mismatch, rate limiting, or Binance maintenance.

Common situations: Wrong API key/secret in env vars; key lacks Futures permission; server clock drift causing timestamp/recvWindow errors; -2015/-2019 API errors; restricted-region blocks.
