Hello Monks, I'm facing a weird issue with a script that posts messages on Zendesk. The script has been working for years on Windows 2003 and doesn't on Windows 2016. And yet, the http return code is 200, and no error is returned.
I've checked that there is no network or firewall issues by sending a simple post through curl.
I'm wondering how I can add traces to get clues about what's going wrong.
Here is a test script that fails on W2016 and works on W2003.
Thank you
