RTO India — Payment Status showing as pending after completion of Payment for DL Test

I have made payments for my Driving License Application before booking a slot for the DL Test today morning. After the payment is completed, the portal let me download the eChallan slip also which is showing the payment status as completed. But after that, when I am redirected to sarathi website, the payment status there is pending and the following is coming :

Either Payment details not received from the bank or payment is not successful.
