RTO India — DL Backlog entry verified successfully twice and then application got rejected

My driving license was issued from vadodara RTO. Currently I am residing at Navi Mumbai Maharashtra . One month back I applied for renewal of DL at RTO
Vashi Navi Mumbai as it was due. it was showing scrutiny. I visited Vashi RTO. They informed me that I need to do DL backlog entry approval. So I applied online for the same. But two times after verifying successfully by RTO vadodara, my application got rejected. I am not able to trace out the reason for the same. Pls help me to get approval for DL Backlog due to which I am not able to proceed my DL renewal.
