Here are steps you can try to fix it:

🛠️ Troubleshooting Steps for Error U13

Check Internet Connection
- Ensure you have a stable network (Wi-Fi or mobile data).
- Try toggling Airplane Mode on/off or switching between Wi-Fi and mobile data.
Update Google Pay App
- Go to Play Store / App Store, see if there’s an update for Google Pay.
- Running an outdated version can cause communication errors.
Clear Cache & Data (on Android)
- Go to Settings → Apps → Google Pay → Storage.

- This removes any corrupted files that might be interfering.
Restart Your Device
- Power off and turn it on again. Sometimes a fresh session clears temporary glitches.
Re‑add / Verify Payment Method or Bank Account
- Remove and then add your card or bank again.
- Double-check that the bank account details (account number, IFSC, etc.) are all correct.
Wait & Try Later
- The issue might be on your bank’s end (server downtime or maintenance).
- Try your transaction at off-peak hours (late night / early morning) when server load might be lower.
Update Your Operating System
- Ensure your phone’s OS is up to date.
- Compatibility issues or old system bugs might block secure connections.
Contact Support (Bank / Google Pay)
- If nothing works, contact your bank to see if there are restrictions or server issues on their side.
- Also reach out to Google Pay support with the error code U13, device model, OS version, etc.

Cause:
- The system did not receive or received an invalid acknowledgement (ACK) for the transaction.
Solutions:
- Monitor the transaction: The National Payments Corporation of India (NPCI) has been working on adding more clarity to error codes for non-financial transactions, so keep an eye on updates or contact your bank for specific details.
