Hi Andrew,
You can use CURLOPT_ERRORBUFFER (https://curl.se/libcurl/c/CURLOPT_ERRORBUFFER.html) before sending the request to get more information. You should also probably be taking a look at the response code from your curl_easy_perform call - it likely contains information on the failure type if it failed. Your curl_easy_getinfo, I presume, is simply checking the HTTP code - where there is none if an http request never actually occurred.
