Hi All,

   I was able to resolve this issue by upgrading DMD from V88 to 
V91.0, and now I am getting the below error when i set any of the 
below options

http.handle.set(CurlOption.ipresolve, "v4");
http.handle.set(CurlOption.http_version, "v1_1");
http.handle.set(CurlOption.sslversion,  "sslv3");

Error:
std.net.curl.CurlException at std\net\curl.d(4388): A libcurl 
function was given a bad argument on handle CF2990
