OPENSSL s_cient request fails (with 408 request timeout) - ssl

Question

I am trying to connect to using openssl s_client api, command:
openssl s_client -connect <server1>:443
I am getting following output:

It results in request time out.
If I use curl command it is successful.
What is the cause for the request timeout ?
