This is probably occuring because the certificate you're using lists "localhost" as its common name with no alternates, and the IP address is not its common name, and therefore the certificate verification fails. If that is the issue, you need to either generate a certificate for the IP address in use, or turn off verification with http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTSSLVERIFYHOST -Nachman ________________________________ From: Ajay Tanpure <ajaytanpure92@gmail.com> To: libcurl development <curl-library@cool.haxx.se> Sent: Tuesday, June 4, 2013 8:33 PM Subject: using libcurl for HTTPS with IP address as server address Hello, I am using Libcurl on the HTTPS client side. I have gone through the example of HTTPS as given on http://curl.haxx.se/libcurl/c/https.html In this code instead of www.example.com in CURLOPT_URL function, i have used the localhost as below as my server is also located on same local machine and it works fine. curl_easy_setopt(curl, CURLOPT_URL, "https://localhost:8080/a.html"); But when i use IP address of the server  like curl_easy_setopt(curl, CURLOPT_URL, "https://127.0.0.1:8080/a.html"); or when server located on remote host then accessing web pages as curl_easy_setopt(curl, CURLOPT_URL, "https://192.168.0.105:8080/a.html"); does not work. It gives error that curl_easy_perform() fails.
