I did this

We seem to be encountering an intermittent CURLE_OPERATION_TIMEOUTED error with curl versions > 8.11.1. We have our own custom software that uses libcurl libraries to send http/s requests to our custom server. The issue has been narrowed down to the following conditions being needed to reproduce the issue:

  • The Issue is seen only with libcurl versions > 8.11.1 (tried with curl 8.12.1, 8.13.0, 8.14.1) . It works correctly up until libcurl 8.11.1
  • Our builds that build libcurl have been largely unchanged
  • The issue is seen only when https is in play (curl connecting to a server that is https based)
  • The issue is also only seen on Virtual Machines. We use some form of VMWare Esx virtual machines
  • The issue is not reproducible on "real" machines

I expected the following
