India Post — unable to track consignment - chennai

Address:

600064

An important government document was mailed from rudrapragay, uttrakand to chennai, tamilnadu on 5, june, 2018 in a registered mail through india post.

Here is the tracking number: rv[protected]in

When i try to track the mail i keep on hitting into either "unable to get consignment details, please try after sometime!!!" or "consignment details not found"

Is there a way to track the package as it is an important package?

Thanks
