Binance looses its orders

When I query KAVAUSDT order #561657676 with /api/v3/order?symbol=KAVAUSDT&orderId=561657676&timestamp={{timestamp}}&signature={{signature}} that normally should return

{
    "symbol": "KAVAUSDT",
    "orderId": 561657676,
    "orderListId": -1,
    "clientOrderId": "ce86e0a9-85a8-4d9b-99b1-b08e227e2464",
    "price": "4.80700000",
    "origQty": "10.00000000",
    "executedQty": "0.00000000",
    "cummulativeQuoteQty": "0.00000000",
    "status": "CANCELED",
    "timeInForce": "GTC",
    "type": "LIMIT",
    "side": "BUY",
    "stopPrice": "0.00000000",
    "icebergQty": "0.00000000",
    "time": 1632183933417,
    "updateTime": 1632184233620,
    "isWorking": true,
    "origQuoteOrderQty": "0.00000000"
}

I periodically get

{
    "code": -2013,
    "msg": "Order does not exist."
}
