Is money deducted with UPI error U88?

Possibly. UPI debits the payer first and credits the receiver second, so a failure on the receiver's side can leave a debit that has to be reversed. If you were debited, the reversal is automatic and due by T+1 for a transfer to a person, or T+5 for a payment to a merchant. After that the bank owes you ₹100 a day.

UPI error U88: Connection timeout in credit request

Official NPCI descriptionCONNECTION TIMEOUT IN REQPAY CREDIT TECHNICAL

Raised by: NPCI UPI switch. Source: NPCI, UPI Error and Response Codes v2.9, section 4.4, errors from the UPI service layer.

What it means

NPCI's switch couldn't connect to the receiver's bank to send the credit request. The debit has usually already happened by then, so it has to be reversed.

Was money deducted?

Possibly. UPI debits the payer first and credits the receiver second, so a failure on the receiver's side can leave a debit that has to be reversed.

When does the money come back?

If you were debited, the reversal is automatic and due by T+1 for a transfer to a person, or T+5 for a payment to a merchant. After that the bank owes you ₹100 a day.

Which side caused it?

NPCI's UPI switch.

Type of decline

Technical: a system didn't respond or failed.

If money left your account. Under RBI's turnaround-time rules (circular DPSS.CO.PD No.629/02.01.014/2019-20, 20 September 2019), if your account is debited but the payment fails, the money must come back by the next working day (T+1) for a transfer to a person, or within T+5 days for a payment to a merchant. After that the bank owes you ₹100 for every day of delay.

What you should do

If money left your account, it comes back. Don't send again until you've checked.

If you are a merchant, bank or PSP

Beneficiary connectivity problem. Reconcile; reversal should follow.

If it still isn't sorted

Raise a complaint inside your UPI app. Every UPI app has a help or dispute option on the transaction, and it goes into NPCI's online dispute system. Keep the UPI transaction ID or RRN handy.
If the app doesn't resolve it, contact your bank's grievance desk with the same reference.
If your bank hasn't replied within 30 days, or you're not happy with the reply, complain to the RBI Ombudsman at cms.rbi.org.in. It's free.

Technical or business decline?

NPCI splits declines into two kinds. A technical decline means a system didn't respond or failed: a bank offline, a timeout, a switch error. A business decline means the systems worked and said no, for a reason about the account or the payment: wrong PIN, not enough money, a limit, a risk check. Retrying helps with some technical declines and almost never with business ones.
