Welcome to the community @nknaresh
First off, this sort of problem is difficult to provide solutions when you do not supply the domain name.
For your example shown below, does it work in a browser to go to
https://www.caregiver.my-hidden-domain.in
Because your domain is proxied it uses Cloudflare CDN. A TLS handshake failure between the Let's Encrypt server and the CDN Edge is very unusual. Errors between the Edge and your Origin Server usually have a different kind of error message.
For the errors which said "DNS Problem: NXDOMAIN ..." those should be easy to correct. You have not defined those names in the DNS at Cloudflare (or anywhere).
