@NaveenKummetha I just experienced the same issue as you.
Found those 2 blog posts
Part #1: https://saltproject.io/blog/salt-bootstrap-breakage/
Part #2 https://saltproject.io/blog/salt-bootstrap-breakage-part-2/

In short, you can and should download the bootstrap script from here, on-going forward.
