This Curl error 7 is happening intermittently, so yes I am able to

Therefore, in case if this happens again in future, I want my
application to display more error messages than just Curl error 7,
which is why I am wondering if there is a way to add debugging log
from openssl in libcurl.
Please don't top-post it makes the conversation hard to follow. [1]
CURLOPT_DEBUGFUNCTION does not work unless CURLOPT_VERBOSE is enabled. [2]
CURLOPT_ERRORBUFFER can sometimes be used to obtain a more detailed
error string. [3]
