Receive payments not work

[The0ld]

Make the configuration of receive balance update so that at the time of receiving a transaction this will be stored in my database, it was working until today that I have not received the corresponding notifications, these are the parameters I sent:

POST: https://api.blockchain.info/v2/receive/balance_update

{
     "key": "key"
     "addr": "address"
     "callback": "http://45.33.87.135:9094/api/v1/recivePayment?secret=secret&index=index"
     "confs": "3"
     "onNotification": "KEEP"
     "op": "RECEIVE"
}

I would like to know what the problem is.
