How to deposit/withdraw with driftpy?

[wkshare]

I always error:

Error in subscription perpMarketMap: server rejected WebSocket connection: HTTP 409
Error in subscription spotMarketMap: server rejected WebSocket connection: HTTP 409

my code:

    spot_market_index = 0 # USDC
    amount_in_spot_market_precision = drift_client.convert_to_spot_precision(100, spot_market_index) # $100
    
    user_token_account = drift_client.get_associated_token_account_public_key(spot_market_index)
    
    try:
        tx_sig_and_slot = await drift_client.withdraw(
            amount_in_spot_market_precision,
            spot_market_index,
            user_token_account
        )
        print(f"Withdrew successfully: {tx_sig_and_slot.tx_sig}")
    except Exception as e:
        print(f"Failed to withdraw: {e}")
