Neither of those versions are accurate descriptions of their respective
version numbers. But it is enough to tell us that you're using outdated
versions of both libcurl and OpenSSL. Both are old and insecure.

First, try using the plain openssl tool to connect with the server to verfiy
that OpenSSL works fine with it. If it does, then continue and upgrade to a
newer libcurl to see if that cures the problem. If OpenSSL has problems, then
upgrade that (too) and check with the latest version.
