Hi!

Host resolution seems to be OK, the curl connection instead reports an
error from inside OpenSSL:

result == 35 : Error (OpenSSL SSL_connect: SSL_ERROR_SYSCALL in
connection to license.microanalytics.org:443 )

I have enabled CURLOPT_VERBOSE, and it outputs the above error when
using a build that enables ares_getaddrinfo. The error is not printed
when running without, and I instead get a IPv4 connection that goes
through.

I'm not sure how to do that, sorry.
