Hi Sameer,

No idea without more information. What code are you using - handle instances usually mean that you have an invalid connection handle which means you either didn't connect or re-used and didn't close the connection. You should be using HttpGet() not HttpGetEx() to make sure you're using the right semantics.

Also to be clear: We no longer support old versions of Client Tools/wwIPStuff that don't run on VFP 9. We stopped support for VFP 8 about 5 years ago with Client Tools v6 and later. Newer versions have many fixes applied that fix OS changes and security updates (like support for TLS 1.2) from what you're likely running from back in 2012 (v5 most likely).
