Any ideas how to debug this?

Eventually upgraded urllib3 from 1.26.20 to latest 2.3.0 version and rerun my code and then the real error was revealed.

[madhav-db]

Closing this as underlying issue has been resolved.

@madhav-db The issue is not with the actual resolution but with urllib3==1.26.20 (and possibly all 1.26.x version of the lib) masking the actual error!
