Cisco Prime 401 unauthorized error from Cisco Prime API

We have 5 Cisco Prime instances with 3.7 which we upgraded very recently from 3.4, after the upgrade we see 401 unauthorized exception from all the 5 PI instances, which we never encountered when we consumed them with Prime 3.4.

I am using below Python script to consume the API, as per Cisco's suggestion I have closed the connection in headers as well as with r.connection.close but it simply does not work
